Account for the following : Bond angle in NH+4NH4+ is higher than NH3.

NH3 has a lone pair of electrons that strongly repels the bonded pair of electrons and reduces the bond angle. On the other hand, NH+4NH4+ does not have any lone pair of electrons; hence, there is no lone pair–bond pair repulsion. Thus, the bond angle in NH+4NH4+ is higher than that in NH3.

Account for the Following : Bond Angle in Nh+4 is Higher than Nh3. -

Question

Account for the following :

Bond angle in ${NH}_{4}^{+}$ is higher than NH₃.

Solution

NH₃ has a lone pair of electrons that strongly repels the bonded pair of electrons and reduces the bond angle. On the other hand, ${NH}_{4}^{+}$ does not have any lone pair of electrons; hence, there is no lone pair–bond pair repulsion. Thus, the bond angle in ${NH}_{4}^{+}$ is higher than that in NH₃.
