Question

How many and what types of bonds are present in $N{H}_4^{+}$?

• A. Four covalent bonds
• B. Three covalent bonds and one ionic bond
• C. Four ionic bonds
• D. Three covalent bonds and one coordinate bond

Answer 1

The correct option is D Three covalent bonds and one coordinate bond

In $N{H}_4^{+}$ molecule, there is $2$ types of bonds are present: three covalent bonds and one coordinate bond.

In this compound, nitrogen has one lone pair of electron and one hydrogen atom has vacant orbital and that's the condition of the formation of a coordination bond.

Hence, the correct answer is option $\text{D}$.
