Answer 1

3000-3100 cm-1 C-H stretching of alkene

2950 cm-1 is C-H Stretching frequency

1500-1600 cm-1 is N-H bending frequency

1452 cm-1 C-H bending of alkane

1000-1100 cm-1 is for C-O Stretching frequency

985 cm-1 is for C=C bending of alkenes

767 cm-1 is for C =C bending

669 cm-1 is for strong C-Br Stretching

All above frequency slightly variable from original
