Question

A tin chloride Q undergoes the following reactions (not balanced).
$Q+C{l}^{-}⟶XQ+M{e}_{3}N⟶YQ+CuC{l}_2⟶Z+CuCl$

$X$ is a monoanion having pyramidal geometry. Both Y and Z are neutral compounds. Choose the correct option(s).

• A. The central atom Z has only one lone pair
• B. The central atom in X is $s{p}^3$ hybridized
• C. There is a coordinate bond in Y
• D. The oxidation state of the central atom in Z is +2

Answer 1

Answer: (B), (C)

There is a coordinate bond in Y

$\underset{\left(Q\right)}{SnC{l}_2}+C{l}^{-}⟶\underset{\left(X\right)}{SnC{l}_3^{-}}$

$\underset{\left(Q\right)}{SnC{l}_2}+M{e}_{3}N⟶\underset{\left(Y\right)}{SnC{l}_2\left[N\right(C{H}_3{)}_3]}$

$\underset{\left(Q\right)}{SnC{l}_2}+2CuC{l}_2⟶\underset{\left(Z\right)}{SnC{l}_4}+CuCl$
