The formula of product obtained by reducing 2-butanone to 2-butanol has to be written and its chirality has to be predicted. Concept introduction: Chirality: The presence of four different atoms (or groups) at carbon is known as asymmetric carbon and is known as chiral center of the compound. Lithium aluminum hydride: Used as strong reducing agent, hydride (weaker Al-H bond) act as strong nucleophile that attack the electrophilic carbon of carbonyl group forming metal alkoxide intermediate complex; acid workup is the final step involving protonation of alkoxide oxygen results the alcohol as aproduct.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C = O, as their functional group. The carbonyl group in ketones is placed somewhere in the middle of the molecular structure, which means, the C=O is attached to two alkyl groups or benzene rings. Just like all other homologous series, the naming of ketones is done using a common suffix “-one”. The general molecular formula is C n H 2n O. Functional group of a ketone
