Question

13. Boron behaves anomalously
with respect to its other group
members, because boron has
comparatively
(a) small size
(b) large charge to radius ratio
(c) high electronegativity
(d) All of these​

Answer 1

Explanation:

The main reason for showing anomalous properties of the first member of a group in s or p-block is small size, large charge/radius ratio. For example, in the first group, Li shows anomalous behavior due to small size, large charge/radius ratio( high polarising power).
