(a)
Interpretation:
The way by which the given alcohol is prepared by treating an ester with a Grignard reagent has to be shown.
Concept introduction:
Alkyl or aryl magnesium halides
Reaction of Grignard reagent with a formic ester followed by hydrolysis in aqueous acid yields secondary alcohol. Tertiary alcohol can be prepared by the reaction of Grignard reagent with ester.
(b)
Interpretation:
The way by which the given alcohol is prepared by treating an ester with a Grignard reagent has to be shown.
Concept introduction:
Alkyl or aryl magnesium halides
Reaction of Grignard reagent with a formic ester followed by hydrolysis in aqueous acid yields secondary alcohol. Tertiary alcohol can be prepared by the reaction of Grignard reagent with ester other than formate.

HO, CIarrow_forwardAcetals are formed from the reaction of two alcohols with a carbonyl under acidic conditions. Acetal formation is faster with 1,2-ethanediol than with two methanol molecules. Choose the factor that explains the difference in reaction rates. A) The reaction with 1,2-ethanediol has a lower AH (enthalpy) of reaction. B) The reaction with 1,2-ethanediol has a higher AH (enthalpy) of reaction. C) The reaction with 1,2-ethanediol has a more favorable entropy of reaction.arrow_forward
