Q1:

Which of the following functional groups would make a carbon-based compound the least polar?

A Phosphate

B Methyl

C Carboxyl

D Amino

ANS:B - Methyl

The inductive effect of methyl groups is very low. They do not have electrophilic or nucleophilic nature. Only covalent bonding. So, polarity would be least.
