Optical isomers

Do all optical isomers have COOH and NH2 bonded to the central chiral carbon ??

Optical isomers are any compound that contain a carbon centre with four different groups attached, the carbon is said to be chiral because there is no plane of symmetry. For example Butan-2-ol has optical isomers (enantiomers).

I'm by no means a marker/ have experience in A level specs but in the OCR A A level Chem spec it says:

"Learners may be tested on their
ability to:
draw diferent forms of
isomers
identify chiral centres from a
2-D or 3-D representation."

So it sounds like you could also be given a molecule and asked to find the chiral centre ie the carbon that has four different groups attached. I'll put the link below incase I'm not looking at the right specification.

No, a chiral carbon only needs 4 different groups or atoms attached.
