Which of the following compounds will show cis-trans isomerism?

View answer and explanation

Correct option: C

\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}=\mathrm{CH}-\mathrm{CH}_3

Option C (

\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}=\mathrm{CH}-\mathrm{CH}_3

) is correct because for cis-trans isomerism to occur, each carbon of the double bond must have two different groups attached to it.

In benzene, there is a delocalisation of π-electrons. Hence, each π-electron is attached by….carbon nuclei. Which statement is false? Assertion (A) In comparison to ethyl chloride, it is not easy to carry outnucleophilic substitution on vinyl chloride.

Reason (R) Vinyl group is an electron donating. If 2-oxopropanal and methanal are obtained by the reductive ozonolysis of compound (A), then the number of
