Detailed Solution

As the no.of lone pairs increases repulsive forces between L.P-B.P & L.P increasesi.e.. L.P causes more repulsions on the B.P's and hence B.P electrons moving closer to each other, therefore B.A decreases order ofRepulsion between different electron pairsB.P-B.P < B.P-L.P < L.P-L.P Since lone pair occupies more space as compared to B.P
