Question

The type of isomerism which is not exhibited by alkene is:

• A. chain isomerism
• B. metamerism
• C. position isomerism
• D. geometrical isomerism

Answer 1

The correct option is B metamerism

Alkenes can show $chain$ $isomerism$ (different longest chain but same formula), $position$ $isomerism$ (substituents at different places) and $geometrical$ $isomerism$ (cis-trans) but not $metamerism$, because it does not contain any functional group like two alkyl groups on either side ($R-O-R^{\prime }$).

Option B is correct.
