Q1
. In the reaction of phenol with CHCI and aqueous NaOH at 343 K, the electrophil
attacking the ring is:
(a) CHC13 CHels
(b) CHC12 CHCL
(C) ECI2 CHCI
(d) CoCl2

Answer 1

Explanation:

In the reaction of phenol with CHCl3 and aq NaOH at 343K, the electrophile attacking the ring is CCl2(Reimer Tiemann Reaction and Carbene formation

Answer 2

Explanation:

In the reaction of phenol with $CHCl_{3}$ and aq $N_{a} OH$ at $343 k,$ the electrophile

attacking the ring is $CCl_{2}$ .

phenol and aqueous:

• When bromine water is introduced to a phenol in water solution, the bromine water decolorizes and a white precipitate with antiseptic tribromophenol forms.

• In 2,4,6-tribromophenol is the precipitate. Take note of the many substitutions that occur around the ring, in all of the activated places.
