Question

Ammonia is a Lewis base. It forms complexes with cations. Which one of the following cations does not form complex with ammonia ? (A) Ag+ (B) Cu2+ (C) Cd2+ (D) Pb2+

Tardigrade Admin · Accepted Answer

Ammonia is a Lewis base. It forms complexes with cations of transition elements. Pb 2+ does not form a complex with ammonia as lead ( P b ) is not a transition element. Lead ( Pb ) is a p - block element.

Q. Ammonia is a Lewis base. It forms complexes with cations. Which one of the following cations does not form complex with ammonia ?

$A g^{+}$

$C u^{2 +}$

$C d^{2 +}$

$P b^{2 +}$

Ammonia is a Lewis base. It forms complexes with cations of transition elements. $P b^{2 +}$ does not form a complex with ammonia as lead ( $P b$ ) is not a transition element. Lead ( $P b$ ) is a $p$ - block element.
