Predicted the correct order among the following

A

lone pair-lone pair gt bond pair- bond pair gt lone pair- bond pair

B

bond pair - bond pair gt lone pair- bond pair gt lone pair-lone pair

C

lone pair - bond pair gt bond pair-bond pair gt lone pair - lone pair

D

lone pair - lone pair gt lone pair-bond pair gt bond pair - bond pair

Text Solution

Verified by Experts

The correct Answer is:
D
According to the postulate of VSEPR theory , a lone pair occupies more space than a bonding pair, since it lies closer to the central atom. This means that the repulsion between the different electron pairs follow the order.
