Answer:

C₂H₄

Explanation:

A hydrocarbon with a double bond is called an alkene. The general formula for an alkene is CₙH₂ₙ where as the n represents the number of carbons.

Taking your problem as an example:

C₂H₄ has 2 carbons, as indicated by the subscript beside the chemical symbol of Carbon.

if C = 2 then n = 2

CₙH₂ₙ = C₂H₂₍₂) = C₂H₄
