1.	Assign a reason forthe following:In Group 15, the bond angle H-M-H decreases in the following order NH_3(107.8^(@)), PH_3(93.6^@),AsH_3(91.8^(@))
Answer» SOLUTION :Due to increase in size of Group 15 elements as BOND length increases the bond pair-bond pair repulsion decreases. Therefore, the angle H-M-H decreases from `NH_3` to `PH_3` to `AsH_3`.
