Which combination(s) of organic bromide and carbonyl compound can be used to prepare the following product by reaction of the Grignard reagent derived from the alkyl bromide with the carbonyl compound?

Question

Quizplus · Accepted Answer

The product has an alcohol functional group, which indicates that the carbonyl compound must be a ketone or aldehyde. From the options given, only 1-methylcyclohexanecarbonyl chloride (Option 1) and cyclohexanone (Option 3) are ketones or aldehydes. To form an alcohol, the Grignard reagent must have at least one hydrogen attached to the carbon it is adding to. From the options given, only 2-bromopropane (Option 1) and 1-bromobutane (Option 3) have this feature. Therefore, options 1 and 3 can be used to prepare the given product.
