WebTranscribed Image Text: Part B involves the addition of sodium acetate in the reaction between 2.6- and chloroacetyl chloride. Why is sodium acetate used in this step? dimethylaniline To quench the side product (HCI) so that it can not protonate aniline. The protonated aniline is a stronger nucleophile so less reactive To quench the side ...

If the halogenation is carried out in non-aqueous medium like CS 2 or CCl 4, only mono−substitution takes place. This is because the ionisation of phenol does not occur in non-aqueous medium.
