16164
The tendency towards complex formation is maximum in
1 \(s -\) block elements
2 \(p -\) block elements
3 \(d - \) block elements
4 \(f -\) block elements
Explanation:
(c) \(d-\) block elements; because
\((i)\) Small atomic size
\((ii)\) High nuclear charge
\((iii)\) Presence of vacant \(d-\) orbitals
