The alkene that exhibits geometrical isomerism isa)2-methyl propeneb)2...
Explanation:
Geometrical isomerism:
Geometrical isomerism is a type of stereoisomerism that occurs due to the restricted rotation around a double bond. It arises when there are two different groups attached to each carbon atom of the double bond, resulting in different spatial arrangements.
Alkenes:
Alkenes are hydrocarbons that contain at least one carbon-carbon double bond. The general formula for alkenes is CnH2n.
Options:
a) 2-methyl propene - This compound does not have a double bond, therefore, it does not exhibit geometrical isomerism.
b) 2-methyl 2-butene - This compound contains a double bond between the second and third carbon atoms. However, both carbon atoms have the same groups attached to them (methyl groups), so there is no geometrical isomerism.
c) Propene - This compound contains a double bond between the first and second carbon atoms. However, both carbon atoms have the same group (a methyl group) attached to them, so there is no geometrical isomerism.
d) 2-butene - This compound contains a double bond between the second and third carbon atoms. The groups attached to these carbon atoms are different (a hydrogen atom and a methyl group), resulting in geometrical isomerism.
Therefore, the correct answer is option 'D' - 2-butene.

2-Butene exist as cis and trans isomers. The cis-isomer has the two methyl groups on the same side and the trans-isomer has the two methyl groups on opposite sides.
Due to restricted rotation around double bond it exhibits geometrical isomerism.
