I just started Chem and I am having a hard time getting started.
Is CH3CH2CH2CH(CH3)2 a primary, secondary or tertiary carbon and why?
Both CH2 (2nd CH2 and 3rd CH2 from left) Has Secondary Carbon atom
There is only 1 CH and this carbon is Tertiary
All the CH3 Carbons are Primary Carbon atom (1st CH3 and last 2 CH3)
Just to chime in, the atom designation increases with the amount of carbon atom bonding.
A primary carbon has one carbon atom bonded to it.
A secondary carbon atom has two carbon atoms bonded to it.
A tertiary carbon atom has three carbon atoms bonded to it.
A quaternary carbon atom has four carbon atoms bonded to it.
First you must look for the longest chain of carbons to correctly determine the configuration. That is five carbons with a methyl group on number 4 so the second methylene group is attached to two other carbons and therefore secondary.
There is one tertiary carbon and the primary carbons are 1, 5 and the methyl group attached to 4.
Ambiguous. Which carbon are you talking about in this pentane molecule? There are examples of each here, but which is unclear.
There are 3 1°, 2 2º, and 1 3º carbon here.
Primary (1º) is a carbon with three hydrogens on it.
Secondary (2º) is a carbon with two hydrogens on it.
Tertiary (3º) is a carbon with only one hydrogen on it.
