Answer 1

- IR Peak of acetone. The carbonel stretching frequency will come at 17100ml The spic-H penk will come me et 2976 cm Here CH3 H - stretching frequency will come at 1781 cm! e & carbonel at peak will come at 08 2827 cm and spa eh proton will come at 2876cm! Here contain the set of proton, Here inen IH NMR showing 1.5 ppm septet. is the multiplienty - 2nI+1 herghbowling where a number of the drogen I spin quantum for hydrogen I th proton with split as - 2n I + 1 Here on=2 = 2x2x2 +1 = 3 (triplet) proton win spist es 2011 B - 2xcx tal I = + - Septeri

Come А proton which Here in this compound 3 type of proton observed, at 3.5 pppm singer and singler because rapid proren exchange happen with D20 prorom to come at 3.4 ppm. and quarteat. The multipliery - 2xnx I til - 2x 3 x 2 + 1 - 4 - quartet. proton will come at 9.1ppm and multiplicity is anI tl 72*2*4+1 - 3 -toppret. Iath tripler the I - te Here p 4 type of proton will come protom will come at 5.1 pemand sregler proton will come at 2.5ppm and somer - 28t1= 2x2 x 2 a 1 =3 prorom win come at 1.5 ppm and multiplate. = (20541) (20+1) = (2x 3 x 2 + 1) (2x 2 x 2 t) 4x3 = multiplate. proton win come at gppm and tripler. 2nIt 12 (2x2 x + 1) =3 striper. D

Here in this compound ssen of proton is present. À proton is come at 3. 4 ppm and singler. Croon having B Beroton is come at 3.0 pom multiplete. (201 +1) C2N IAD - 6x3 x4 +1) (2 x 1 x 241) = 3x2 - multiplate proton is come at 2.2pom and multiplar (2MIN C 2m ID no another - (2 x 1 x 2) (2x G x 1 +D neighbouring 2x7 s Multplater hydrogen proton is come at 12ppm and doubler =(22+T 41) = (2x L x 1 + 1) = = 2= doublet proton is come ato.gpom and donblen = (2x READ = (2x 1x 4+1) = doubler.
