Vedclass · Answer

(D) To react with ethylmagnesium bromide (a Grignard reagent),the compound must contain an acidic hydrogen or an electrophilic functional group like a carbonyl or nitrile. To decolourize bromine water,the compound must contain an unsaturated bond (alkene or alkyne).$A$: Contains a ketone and a nitrile group (reacts with Grignard) but no alkene (does not decolourize $Br_2$ water).$B$: Contains a nitrile and an ester group (reacts with Grignard) but no alkene (does not decolourize $Br_2$ water).$C$: Contains an alkene (decolourizes $Br_2$ water) but no acidic hydrogen or reactive electrophilic group for Grignard reagent.$D$: Contains a phenolic $-OH$ group (acidic hydrogen,reacts with Grignard) and a vinyl group (alkene,decolourizes $Br_2$ water). Thus,$D$ is the correct answer.

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