Give reasons(i) Ammonia is a good complexing agent.(ii) In group 15 elements ,the bond angle H-M-H decreases in the following orderNH3(107.8o),PH3 (93.6o), AsH3 (91.8o). |

Answer» (i) Ammonia has a lone pair of electron therefore it is a good complexing agent. (ii) With the increase in the size of group 15 element as bond length increases the bond pair-bond pair repulsion decreases. Therefore the angle H-M-H decreases from NH3 to AsH3 . |
