Question

Answer 1

Answer #1

In A, negative charge is on Cl

In B, negative charge is on Br

In C, negative charge is on F

In D, negative charge is on I

As size of atom increases, the negative charge density is less and hence it is less available for donation.

So, smaller size implies that the base is stronger

Order of size is: F < Cl < Br < I

Since F is smallest, it is strongest base

Answer: C
