Answer 2

Answer 14.

1,2-dibromopropene will show geometrical isomersim.

Geometrical isomerism is shown by the organic compounds which are non-symmetrical and have different ligands on the carbon containing double bond.

In option A , first carbon has bromine and hydrogen attached to it and second carbon has bromine and methyl attached to it. So it satisfies the condition of geometrical isomerism.

In option B, second carbon has 2 methyl attached to it so it cannot show geometrical isomerism.

In option C, both the carbons have bromine and methyl attached to it. So it is a symmetrical compound.

In option D, second carbon has 2 methyl attached to it. So it cannot show geometrical isomerism.
