When two halogen atoms are attached to same carbon atom then it is :

(A) The bond angle C-O-H in alcohol is less than in phenols (R) In phenols -OH group attached to the sp^2 carbon atom. While in alcohols OH group attached to sp^3 carbon atom

C_6 H_5 -group causes - l-effect when present in a saturated chain of carbon atoms.

A carbon atom which is bonded to four different atoms or groups is called an asymmetric carbon atom
