Answer 1

Answer:

FT IR Spectrum I:

In the FT IR spectrum I the stretching values showed in the range 3300-2900 cm-1 indicates the presences of aclcoholic, carboxylic -OH functional group.

the stretching showed in the region of 1700-1560 cm-1 analogous to carbonyl stretching of acid, ketone, ester etc.

The -C-O- stretching in the region of 1250-1050 cm-1 analogous to alcoholic, ester and ether etc.

FT-IR Spectrum of II:

The broad peak shows at 3400cm-1 analogous to -OH of carboxylic acid and rest of the things are almost similar to FT-IR of first (I)
