Question

Which of the following compounds can have a double bond?
C₄H₁₀; C₅H₈; C₅H₁₀

Answer 1

C₅H₁₀ can have a double bond because it satisfies the general formula for alkenes i.e., C_nH_2n. Here, there are 5 carbon atoms; hence, n is 5. Substituting n in the formula C_nH_2n, we get, `C_5H_(2xx5)=C_5H_10`
