Assertion : Geometrical isomerism is also called cis-trans isomerism. Reason : Propene shows geometrical isomerism.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Geometrical isomerism is possible only when each double bonded carbon atom is attached to two different atoms or groups. No geometrical isomers are possible for propene \(\left(\mathrm{CH}_{3} \mathrm{CH}=\mathrm{CH}_{2}\right)\) because one of the double bonded carbon atoms has two identical groups (H atoms) attached to it. So , the option (3) is correct.

How many geometrical isomers are possible for
Remember that cis-trans geometrical isomerism is possible only in alkenes and further only in those alkenes in which the doubly bonded carbon atoms individually have different atoms/groups.

Ratio of possible cis-trans isomer to the number of \({\mathrm{\pi}}\)-bonds possible for the following compound is ____ .
1 \({\rm{8/5}}\)
2 \({\rm{5/8}}\)
3 8
4 5
Explanation:
Number of \({\mathrm{\pi}}\)-bonds present \({\mathrm{=5}}\) Number of cis-trans- isomers possible are \({\mathrm{=8}}\) Ratio \({\mathrm{=\dfrac{8}{5}=1.60}}\)
