Write the structural and stereoisomers of pentene, `C_(5)H_(10)` and compare their stabilities.

Text Solution

Verified by Experts

Pentene exists in the following isomeric forms:


and the stability order is:
Pent-1-ene `lt` pent-2-ene(cis) `lt` pent-2-ene(trans) `lt`2-methylbut-2-ene
(Sinc, stability increases with increasing number of electron releasing alkyl groups.
