A tin chloride Q undergoes the following reactions (not balanced)
Q+Cl-→X
Q+Me3N→Y
Q+CuCl2→Z+CuCl
X is a monoanion having pyramidal geometry. Both Y and Z are neutral compounds. Choose the correct option(s).
  1. The central atoms in X is sp3 hybridized
  2. The oxidation state of the central atom in Z is +2
  3. The central atom in Z has one lone pair of electrons
  4. There is a coordinate bond in Y

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

X is mono anion with sp3 hybridisation and It has trigonal pyramidal geometry.

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

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