Answer 1

Spectru5 No, carbonyl peak. No, -OH or NH peaks 3005: sp2 C-H stretching 2950 and 2850: sp3 C-H stretching 1633: c-c stretching aromatic ring 1535 and 1364: -N-o stretching Hence compound is: Compound N| CH NO 2

Spectrum 3164: sp C-H stretching 2264: alkyne CC bond stretching Terminal alkyne is present as only compound L CH H3C

Spectrum 7 3030: sp2 C-H stretching 2940 and 2870: sp3 C-H stretching 1698: amide carbonyl C-o stretching 1598: C-C stretching 1321: C-N stretching Amide with aromatic ring is present in compound P CH CH3 CH3

Spectrum 3400: braod peak -NH2, -OH present 3060: sp2 C-H stretching 2980 and 2858: sp3 C-H stretching 1613: c-c stretching 1552: C-Hbending 1387: C-N stretching Aromatic ring with amine present only in compound M. NH2
