What is the general formula of the alkane homologous series?

Answer and explanation

Correct answer: D. CₙH₂ₙ₊₂

  1. Step 1: Alkanes are saturated hydrocarbons with formula CnH2n+2.
Answer
CₙH₂ₙ₊₂.
Why not the others: CₙH₂ₙ: this is the general formula of the alkenes. CₙH₂ₙ₋₂: this is the general formula of the alkynes. CₙHₙ: this is not the general formula of a hydrocarbon series.
