Question

A covalent molecule having a double bond between its atoms is ______.

Options

• Hydrogen

• Oxygen

• water

• ammonia

Answer 1

A covalent molecule having a double bond between its atoms is oxygen.

Explanation:

An oxygen atom (atomic number 8) has 6 valence electrons and requires 2 more electrons to achieve a stable octet configuration. When two oxygen atoms combine, they mutually share two pairs of electrons between themselves. This sharing of two electron pairs results in the formation of a strong covalent double bond (O = O) within the (O₂) molecule.
