Question

Identify chiral C in CH3CHOHCH2CH3 and CH3CHOHCH3

Answer 1

chiral carbon: The carbon atom which is attached to four different groups is called as chiral center.
In CH3CHOHCH2CH3 the second carbon from is chiral carbon because it is attached to four different groups.

in second compound there is no chiral center because here the middle carbon is attached to two same groups methyl CH3 groups
