Picture it: You're sitting in class and you keep hearing some stuff about phopsphodiester bonds... um... what? You know it forms links in the DNA deoxyribose backbone but... wait, what? If you have not had much chemistry start reading here; if you've taken organic chem feel free to skip ahead. Let's take it from the top.
You always hear that all life is organic... Wait, Like Organic...
It seems a bunch of Polynuclear Aromatic Hydrocarbon (PAH) chemists were all vying to head up their local ACS PAH subchapter -- but they decided to choose by a random draw rather than suffer the tumult of an election. So they all threw their rings into the hat....
From the moment I was introduced to organic chemistry, back in 2008, I was immediately captivated...and this captivation has never subsided; instead it has intensified exponentially with time. Even when I was taking the class, I was constantly helping other students grasp and reinforce the concepts that even I too was just learning. It was as though my mind had made an instant connection with...

When an electron pair donor known as a nucleophile reacts with a SP3 hybridized carbon with a good leaving group attached to it, a reaction will occur known as nucleophilic substitution. There are two main mechanisms which show how this reaction occurs. In this text we will discuss the mechanisms and summarize the main features...
Nucleophilic Substitution Reactions
Written by tutor Raffi H.
This article assumes that the reader is reasonably familiar with the basic notions of structure, nomenclature and stereochemistry normally taught during the early stages of an Organic Chemistry course. In particular, the reader should be familiar with Organic Halides, as well as the concepts of Chirality, R,S-Configuration and...
Introduction to Organic Chemistry
chemistry is the study of "living" things—not in the same way that biology is the study of life. Rather, organic chemistry takes a look at what composes the living things, and how they’re structured. Organic chemistry breaks down living things not only into organs seen in organisms, but goes a step further to break down those organs into...

Halogenoalkanes are an exciting class of compounds as they are highly reactive, compared to alkanes, when reacted with nucleophiles or bases. Recall halogens, in organic chemistry we often refer to as X, are F, Cl, Br and I. Halogenoalkanes are based on alkanes so they have all single bonds and are therefore SP3 hybridized. With the exception of...

An organic elimination reaction is one where a starting product breaks into two new products that contain all the atoms of the original. Two categories of elimination reaction are identified: the E1 and E2.
E2 elimination reactions involve the combined steps of one carbon atom losing a hydrogen atom to a base, and a second carbon atom...

Students often complain they are terrible at drawing organic chemistry structures especially chair conformations of the cyclohexane rings. Since getting the questions right often depends on the person marking your papers being able to interpret your ring correctly I feel its worth spending extra time getting your ring right.
I will walk you...
Carbonyl Condensation Reactions
Written by tutor John B.
Before reviewing carbonyl condensation reactions, let’s look at two structures that are important in understanding the behavior of the carbonyl group in condensation reactions. Alpha protons (protons attached to the carbons adjacent to carbonyls) are relatively acidic (pKa ≈ 20) due to resonance stabilization of the conjugate base...
Aromatic Electrophilic Substitutions (EArS Reactions)
Written by tutor Erin D.
Recall: When alkenes undergo reactions with electrophiles, an addition reaction occurs.
However, aromatic systems do not reaction in the same fashion as alkene containing systems, in part due to their remarkable stability.
Therefore, when aromatic compounds undergo reactions with electrophiles,...
Alkanes and Alkenes
Written by tutor Nathan R.
Dealing with organic compounds in chemistry can feel overwhelming. A small difference in the molecule changes the name and can drastically change the reactivity of the compound. This holds true for the two compound groups,
Alkanes and Alkenes. They are both hydrocarbons and therefore follow the standard nomenclature prefix (ex. meth,...

Times are definitely changing in the world of education. Today, as with all things twenty-first century, there are no limits to a student's education. This is absolutely exciting since so many 'schools without walls' have adopted various technologies during the past few years to enable students excel academically. As an advanced tutor, it makes me dance in my shoes. Universities such as Harvard,...
An important piece I bring to the table in terms of tutoring is the fact each student is a unique individual, which may be better reached by creative thought concerning what will help them master the material of their subject. It also matters a great deal what their personal goals are in learning a subject.
The teaching approach can be tailored in a way that addresses both what they want to...
One of my dad's favorite sayings is, "If something seems too good to be true, it probably is." The website Coursera is an example of why that saying needs the word "probably". The idea of taking real college courses from top-notch instructors at prestigious schools for free sounds impossible, yet students around the world are doing just that.
Hello! This whole site is pretty new to me, but I wanted to briefly show my interests and experiences, as they are fairly diversified:
Sciences: As noted above, most of my experience is with chemistry. Organic Chemistry is my specialty, but I am also familiar with Inorganic Chemistry. I've been a Teaching Assistant for college freshman level courses through upper level chemistry courses. I...
So far the Fall has been pretty good, a bit light as compared to the Spring, but most tutoring doesn't take place until after the first exam has passed or is just about to happen. Things are picking up and I am going to make good on my plan to have people meet me.
If you are interested in a lower hourly rate and are willing to travel to meet me, (within the city) let me know! I...
This current summer season has been particularly productive in terms of successes achieved with students who either enrolled in fast-paced Organic I and II courses or desired a jump-start for Fall Organic I.
A variety of concepts were dealt with, including nomenclature, acidity and basicity rankings, conformational analysis, stereochemistry, resonance stabilization, reaction mechanisms, functional...
I was asked this question recently by several mothers about which book (singular, not plural) they should get for their sons for their upcoming tests. To both of them I replied: "Get the Princeton Review edition of the book." And while I believe this to be the CORRECT answer, this answer unfortunately is misleading because what I actually want to say is, "Get ALL editions of the...
