What is the reason of providing a mild acid condition for the preparation of imine? O Mild acid will protonate the hydroxyl group of the aminoalcohol intermediate without protonating the nitrogen of the amine starting materials O Mild acid will protonate the aldehyde and ketones readily rather than the strong acid. O Strong acid will rapidly neutralize the amine starting materials before any reaction can occur. O Strong acid condition will alter the structure of aldehyde or ketone as the strong acid will attach to the carbonyl oxygen of aldehyde or ketone making it least nucleophilic.
