Q.
Which of the following has $ s{{p}^{3}}- $ hybridisation?
Punjab PMETPunjab PMET 2003Chemical Bonding and Molecular Structure
Solution:
hence, hybridisation $=s p^{3}$
$PCl _{3}$ has $s p^{3}$ hybridisation but due to presence of one lone pair, it is pyramidal in geometry. (Inspite of being tetrahedral)
