Tert vs. Neo?

Postby Alyssa_Hsu_2K » Thu Mar 09, 2017 12:04 am

I know that tert is when the first carbon of the substituent is a tertiary carbon, and neo is when all but two carbons deviate from continuous chain.

If this is the case, doesn't it mean that tert and neo can be used interchangeably?

However, neo can only be used for pentane and up while tert can apply to butane.

Not necessarily - tert is used for when the first Carbon, the Carbon attached to the R-group, we'll say, is attached to three other carbons. Neo is used specifically for a tail end Carbon that is connected to three other carbons.

the way I learned it was that tert applied to 4 or less carbons, and neo applied to 5 or more.

Both "tert" and "neo" are prefixes that apply to the structural arrangement of the subsistent bonded to the carbon atom. However, I think the difference between the two is that tert refers to the plus-like shape that has four carbons, whereas neo is used when there are 5 or more carbons attached.
