Chapter 8, Problem 48A

Interpretation Introduction

Interpretation: Coordinate covalent bond is to be explained with an example

Concept introduction:

Molecules are formed via a long-lasting attraction between atoms or ions known as a chemical bond. The bond may be formed by the exchange of electrons or by the electrostatic attraction of two ions with opposite charges.

Answer to Problem 48A

The sharing of an electron pair from a single atom only results in the formation of coordinate bonds.

Explanation of Solution

An alternative type of covalent bond called a coordinate bond is formed when an electron pair from one atom is shared. The same atom gives both the shared electrons. It is also known as a dative bond.

It is symbolized by the symbol ' $\to$ '. The acceptor species is represented by the head of the arrow, while the donor species is represented by the tail of the arrow.

Examples are cis and trans isomers and all metal-water compounds of the form ${\left[\text{M}{\left({\text{H}}_{\text{2}}\text{O}\right)}_{\text{n}}\right]}^{\text{X+}}$
