Quaternary carbon

[dat_student]

(CH3)2-C*=CH2

Isn't C* quaterary? Kaplan says C* is not quaternary. Doesn't the double bond count as attachment to 2 carbons?

yeap that is quatenary. What does kaplan say?

Kaplan doesn't count it as quaternary. They probably overlooked it then.

Actually, I could be wrong. Since quatenary means to be bonded to four other carbons.. ( was thinking 4 bonds = quatenary), and it has a double bond, it would be considered tertiary because it is only bonded to three other carbons.

For some reason, I have a feeling double bond counts as 2 attachments & makes it quaternary. I'll have to double check...

shouldn't be classified as quaternary.

Edit: actually i'm not sure either. Can you post what u find ? thank you

wait ill try to look it up too. i'm reconsidering. Sorry about that.

A quaternary carbon atom is a carbon to which four other carbon atom's are attached with single bonds.

4 other carbons or 4 different carbons?

4 different carbons.

Yeah pretty sure quaternary is when it's bonded to 4 other carbons through SIGMA (single) bonds.

I never even thought of all this...you bring up some good points dat_student. I bet you got the double bond counting as two attachments from assigning configurations in ochem.

im pretty sure that molecule isn't quaternary...

you need four other carbons attached to the carbon of interest to be quaternary..
