JEE Advanced2019ChemistryChemical Bonding and Molecular StructureActual
A tin chloride Q undergoes the following reactions (not balanced) Q + C l - → X Q + M e 3 N → Y Q + C u C l 2 → Z + C u C l X is a monoanion having pyramidal geometry. Both Y and Z are neutral compounds. Choose the correct option(s).
Options
- AThe central atoms in X is s p 3 hybridized
- BThe oxidation state of the central atom in Z is + 2
- CThe central atom in Z has one lone pair of electrons
- DThere is a coordinate bond in Y
Correct answer
A. The central atoms in X is s p 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 X is mono anion with sp 3 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.
