Assign reason for the following: Ammonia (NH_3) has greater affinity for protons than phosphine (PH_3). |
| Answer» Solution :Both the molecules have pyramidal shape and both have LONE pair of ELECTRONS on N and P. NITROGEN being smaller in size, ELECTRON DENSITY is more on nitrogen in ammonia than that on P in phosphine. That is why ammonia has greater affinity for protons than phosphine. | |
