Question

Explain coordinate covalent bond with an example.

Answer 1

In a coordinate covalent bond, one element transfer the electron pair to another element to make a bond.

It is represented by the ${}^{\prime }{\to }^{\prime }$ symbol. The head of the arrow represents the acceptor species and tail of the arrow represents the donor species.

Example $H_{3}N:+H^{+}\to [H_{3}N\to H{]}^{+}$

Here, ammonia transefer the electron to $H^{+}$ to make a coordinate covalent bond.
