MCQ
A gas having double bonds is :
  • A
    Carbon monoxide
  • ✓
    Oxygen
  • C
    Carbon dioxide
  • D
    None of these
✓

Answer

Correct option: B.
Oxygen
(b) Oxygen
Explanation : Oxygen gas $\left( O _2\right)$ consists of two oxygen atoms bonded together by a double covalent bond. In a double bond, two pairs of electrons are shared between the two atoms, creating a strong covalent bond. This gives molecular oxygen its molecular formula $O _2$ and is why it is referred to as "dioxygen" or simply "oxygen gas".
