A tin chloride QQ undergoes the following reactions (not balanced)
Q+Cl−→XQ + C{l}^{-} \to X
Q+Me3N→YQ + M{e}_{3}N \to Y
Q+CuCl2→Z+CuClQ + CuC{l}_{2} \to Z + CuCl
XX is a monoanion having pyramidal geometry. Both YY and ZZ are neutral compounds. Choose the correct option(s).A tin chloride Q undergoes the following reactions (not balanced) Q + C l ^ - → X Q + M e _ 3 N → Y Q + CuC l _ 2 → Z +A tin chloride Q undergoes the following reactions (not balanced) Q + C l ^ - → X Q + M e _ 3 N → Y Q + CuC l _ 2 → Z +A tin chloride Q undergoes the following reactions (not balanced) Q + C l ^ - → X Q + M e _ 3 N → Y Q + CuC l _ 2 → Z +

Options

  1. AThe central atoms in X is sp3{sp}^{3} hybridized
  2. BThe oxidation state of the central atom in ZZ is +2+ 2
  3. CThe central atom in ZZ has one lone pair of electrons
  4. DThere is a coordinate bond in YY

Correct answer

A. The central atoms in X is sp3{sp}^{3} hybridized

Step-by-step solution

Sn has vacant d orbitals in tin(II)chloride which can be used to accommodate electron pairs and form coordinate bond.

LP = Lone pairs

A tin chloride Q undergoes the following reactions (not balanced) Q + C l ^ - → X Q + M e _ 3 N → Y Q + CuC l _ 2 → Z +

X is mono anion with sp3{sp}^{3} hybridisation and It has trigonal pyramidal geometry.

A tin chloride Q undergoes the following reactions (not balanced) Q + C l ^ - → X Q + M e _ 3 N → Y Q + CuC l _ 2 → Z +

The above reaction is a Lewis acid-base reaction. The adduct Y formed is a coordination compound, and it is a neutral compound.

A tin chloride Q undergoes the following reactions (not balanced) Q + C l ^ - → X Q + M e _ 3 N → Y Q + CuC l _ 2 → Z +

The central atom in Z is tin, its oxidation state is +4, and it has no lone pair electrons. Z is a neutral compound.
