(a)
Interpretation:
The step of hydride reduction of an ester in which the compound undergo-reduction is to be stated.
Concept introduction:
A process in a
(b)
Interpretation:
A mechanism for the reduction of octanoyl chloride by lithium aluminium hydride is to be proposed.
Concept introduction:
A process in a chemical reaction in which addition of hydrogen, addition of electron or removal of electronegative atom takes place is known as reduction. Lithium aluminium hydride is a reducing agent, used for the conversion of an ester into alcohol.
