This question came from a printed out worksheet, but I'm not sure if the Nobel gas is actually suppose to be decrease or the atomic number.

if the sum of four consecutive even integers is 268, what is the smallest of the four integers?

The carbonyl stretching frequencies for an acid anhydride are approximately $1820~\\mathrm{cm^{-1}}$ and $1760~\\mathrm{cm^{-1}}$. These are both higher frequencies than a simple ketone owing to... more

I guess the ester is a weaker nucleophile because it does have an additional oxygen atom, unlike the ketone, that is pulling electrons from the C-O double bond towards the carbon atom (this happens... more

Please show answer and the work to get the answer , thank you

a.) calculate the molar masses of both octae and carbon dioxide b.) calculate the amount of CO2 in grams, produced by the combustion of 100 g of octane

I've never actually been told deeper reasons for this. In organic chemistry classes (1 and 2) we're usually told that aromatic compounds are very stable whereas anti-aromatic ones are not, and... more

By a primary amine I mean a compound where the hydroxyl group of the corresponding alcohol is replaced with an amine group.
