Question
Geometrical Isomerism occurs in Alkenes only but not in 
Alkanes and Alkynes.
Why?

  Re: Geometrical Isomerism occurs in Alkenes only but not in Alkanes and Alkynes. Why?
Answer
# 1
Geometrical isomerism exist only when there is a chance that two structural/ 
configurational orientations are possible which are distinguishable, due to 
restricted or impossible rotation about the bonds concerned, that is in alkene 
the double bond. The two orientations are when the bulkier groups on the same 
(Z) side or the opposite side (E) of the double bond. in alkanes, due to the free 
rotation about the single bonds, such isomerism does not exist. In alkynes, 
there are not enough substituents, that can distinguish for geometrical 
isomerism
