Answer 1

Bromination of aniline : NH BY2 > Brno 121 HBY, ALOH lamine/ 2,4,6-tribromo aniline Important peaks in IR spectrum ; 3282.97 cm : This pears corresponds to N-H Stretching vibratim. As it 13 A r primary amine it has two band I N -H stretching af (w bond 3282.97 com 1612-36 cmt: This peaks corresponds to czc stretching 1543.07 ant : N-H bending vibration (primary amine) 1380-57 cmt: C-N Stretching vibraltim resonance increases double bond character. 730.46 cmt to, C-H out of plane bending: 858:35 - 646-54 cmt: bread peaks corresponds to N-H out of plane bending. The region 476-48 cm" to 858.45 int corresponds out of plane (oop) bending region its complicated to determined every peak' The important peaks for 24,6-tribromo aniline are identified above,
