can you answer all the questions pls

Answer 1

DATE - Oh - Nh strech strech n 3400 ant a 33co cmt. the conly Compound that doen't DMA U Dimethylethanamide) have N-4 on -on is (vi) & Since it lacks on a ny I thas no beak above 3000 cont) A suber broad beak starts around. 2000 cmt and runs till 3600 cmt clearly indicates Carboxylic group. Sina a broad y=0 streck around 1700 cmt es abo present therefore he given compound is Carboxylic acid. In above question we have seen that - on strech of -coon is extremly broad therfore b/w the two graphs if you encounter an extromle broad peak from aroud wont to 360o cmt just like a graph i 0 24. Then it would be coon. * -on also love broad peak around 34 cocom but it is never as broad as - Coon
