(a)
Interpretation:
The role of aqueous sodium bicarbonate to wash the crude t-pentyl chloride needs to be explained.
Concept Introduction:
The formation of t-pentyl chloride is formed by the reaction of t-pentyl alcohol with HCl. The reaction follows the Unimolecular nucleophilic substitution reaction as the carbocation formed is more stable due to tert-carbocation.
(b)
Interpretation:
The reason for the undesirable wash of the crude halide with aqueous sodium hydroxide needs to be explained.
