As the number of lone pairs of electrons increases, bond angle decreases. Thus, the order of bond angle is <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/312baeec8c3a7b55abc6824d8cadab41-.png" />

Q. The bond angles of $N H_{3}, N H_{4}^{+}$ and $N H_{2}^{-}$ are in the order

$N H_{2}^{-} > N H_{3} > N H_{4}^{+}$

$N H_{4}^{+} > N H_{3} > N H_{2}^{-}$

$N H_{3} > N H_{2}^{-} > N H_{4}^{+}$

$N H > N H_{4}^{+} > N H_{2}^{-}$

As the number of lone pairs of electrons increases, bond angle decreases. Thus, the order of bond angle is

Q. The bond angles of NH3​,NH4+​and NH2−​are in the order
