Q. In which of the following pair both molecules do not possess same type of hybridisation?
A) $CH_{4}and\ H_{2}O$
B) $PCl_{5}\ and\ SF_{4}$
C) $SF_{6}\ and\ XeF_{4}$
D) $BCl_{3}\ and\ NCl_{3}$
Explanation
(d)
$BCl_{3} = 3\sigma\$bonds$+ 0lp\$of$\ e^{-} = 3 \Longrightarrow sp^{2}$hybridisation
$NCl_{3} = 3\sigma\$bonds$+ 1lp\$of$\ e^{-} = 4 \Longrightarrow sp^{3}$hybridisation
