Question

which of the following involves a change in bond angle with reference to a set of cp-ordinates arbiruranky set up within the molecule. ​

Answer 1

Answer:

BCI is trigonal in shape where bond angle is 120. In NH and PCI (both are having pyramidal geometry), though the central atom has equal number of Ione pairs \and bond pairs, the valence shell of P is relatively bigger and pond angle is Iower.
