Identify the electrophilic centres in the following: `CH_(3)CH=O, CH_(3)CN, CH_(3)I`.

Explanation

As a result of resonance, the started carbon atom in the above molecules carry a +ve charge and hence are electrophilic centres.
(c) `overset(delta+)(C)H_(3)-overset(delta-)(I)` Since I being much bigger in sie than C and disperse the negative charge more easily therefore, `CH_(3)` carries a +ve charge and hence is the electrophilic centre.
