In this reaction, α-bromo or chloro acids are prepared by the reaction of carboxylic acid with bromine or chlorine in presence of small amount of red phosphorus.

Q. the reagents used in the conversion are

(i) $PB r_{3}$ (ii) $N H_{3}$

(i) red P, $B r_{2} /$ (ii) $N H_{3}$ (excess)

(i) $PB r_{3}$ , NaCN/ (ii) $L i A l H_{4}$

None of the above

In this reaction, $α$ -bromo or chloro acids are prepared by the reaction of carboxylic acid with bromine or chlorine in presence of small amount of red phosphorus.
