Write the next higher homologue of: (a) C 3 H 6 (b) C 5 H 8

Question

Philoid · Accepted Answer

To obtain the next higher homologue of a given entity or substance, one can add a –CH₂ unit to the given compound. For instance,

(a) To obtain the next higher of a homologue of C₃H₆,

C₃H₆ + (-CH₂ unit) → C₄H₈

i.e., the next higher homologue is butane.

(b) To obtain the next higher of a homologue of C₅H₈,

C₅H₈ + (-CH₂ unit) → C₆H₁₀

i.e., the next higher homologue is hexyne.
