Answer / t. mathew
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

Answer / zaf afridi
Alkynes don't show geometrical isomersim cos there are not enough subsistuents that can distinguish for geometrical isomerism(cis and trans )
In Alkenes on applying heat C-C bond change their position and upon cooling their rotation gets restricted
In Alkanes there is no restriction so they can rotate freely i think

Answer / sana hasan
The geometrical isomers in alkene is due to the restricted
or hindered rotation about carbob carbon double bond
present in them.
The double bond between 2 carbon atoms consist of one sigma
bond(formed by sp2-sp2overlap) along the internuclear axis
and a pie bond formed by sidewise overlap of two
unhybridised p-orbital lying above and below the plane of
sigma bond.

Answer / by bethel amanuel
Geometrical isomerism occur only in alkene is because of free rotation of double bond is not possible.
