Question

The total number of single bonds in ${\text{H}}_2\text{O}$ molecule is/are:

• A. One
• B. Two
• C. Three
• D. Four

Answer 1

The correct option is B

Two

A water molecule consists of two hydrogen atoms and one oxygen atom. The number of valence electrons in oxygen is six and in hydrogen is one. In order to form a stable water molecule the oxygen will share two of its electrons with two hydrogen atoms.

Oxygen will share one electron with each hydrogen atom and each hydrogen atom will share one electron with oxygen atom. A pair of shared electrons is said to constitute a single bond so two single bonds will form between hydrogen and oxygen.
