Answer 1

IR data: 3451 - 3226 - Indicate presence of -OH - Stretching frequency 1650 cmt Indícafe sretching frequency of carbon-carbon double bond! 1680-725 cmt Indicate meta disubstured benzene ring. Mass spectrum: m/z = 110 B C NMR : There are three sets of carbon There is no -Chh group present Peak at 115 & 122 indicate presence of - CH or ach group. one peak at 145 ppm Indicate presence of quarternary carbon atom of benzene ring TH-NMR 15.2 ppm (broad singlet, 24) Indicate presence of two - OH group attached . t benzene ring 6.8 - 6.9 ppm (multiplet, 44) Indicate presence of these 4. benzene ring protons.

By considering given organic all above data structure of compound is- 1650 cmt (c=0) 5.2 8 (broad Lo-uk singlet) 16.8-6.9 multipler All your benzene ng protons) ok 3451 cmt (-OH)
