1.	Alkenes show __________ isomerism.(a) only structural(b) only geometrical(c) both geometrical and structural(d) neither geometrical nor structuralThe question was asked in an online quiz.This interesting question is from Hydrocarbons topic in chapter Hydrocarbons of Chemistry – Class 11
Answer» The correct CHOICE is (c) both GEOMETRICAL and STRUCTURAL The explanation is: Alkynes show both structural isomerism as well as geometrical isomerism, structural isomerism EXHIBITED by ALKENES are chain isomerism and position isomerism, while alkenes also exhibit stereoisomerism as geometrical cis-trans isomerism.
