Topic: JEE PYQ

Answer: B. Full step-by-step solution below.

A $(BCl_{3} : s p^{3}); (PCl_{5} : s p^{3} d^{2}); (NH_{3} : s p^{2}) and (SF_{6}) : (s p^{3} d)$
B $(BCl_{3} : s p^{2}); (PCl_{5} : s p^{3} d); (NH_{3} : s p^{3}) and (SF_{6} :) (s p^{3} d^{2})$
C $(BCl_{3} : s p^{2}); (PCl_{5} : s p^{3} d^{2}); (NH_{3} : s p^{2}) and (SF_{6}) : (s p^{3} d)$
D $(BCl_{3} : s p^{3}); (PCl_{5} : s p^{3} d); (NH_{3} : s p^{2}) and (SF_{6} :) (s p^{3} d^{2})$

Correct answer: B

Solution

(b) Molecule Hybridisation BCl_{3} s p^{2} PCl_{5} s p^{3} d NH_{3} s p^{3} SF_{6} s p^{3} d^{2}
