Vedclass · Answer

(A) The compound must satisfy two conditions:$1$. It must react with ethylmagnesium bromide $(C_2H_5MgBr)$,which is a Grignard reagent. This requires the presence of an acidic hydrogen (like in $-OH$,$-COOH$,etc.) or a carbonyl/cyano group.$2$. It must decolourize bromine water,which indicates the presence of an unsaturated bond (alkene or alkyne).Option $A$ is $2$-vinylphenol. It contains a phenolic $-OH$ group (acidic hydrogen) which reacts with $C_2H_5MgBr$ to form ethane gas. It also contains a vinyl group $(-CH=CH_2)$ which reacts with bromine water,causing decolourisation.Therefore,the correct answer is $A$.

Which of the following compounds reacts with ethylmagnesium bromide and also decolourizes bromine water solution?
