Answer 1

ANSWER:

IR analysis:

• 3350cm^-1$\Rightarrow$ broad and strong peak which belongs to -OH group.
• 3050cm^-1$\Rightarrow$ peak belongs to aromatic C-H bond stretching.
• 25800-2900cm^-1$\Rightarrow$ peak belongs to SP³ hybridised C-H bond stretching.
• 1730cm^-1$\Rightarrow$ peak belongs to carbonyl C=O bond stretching.
• 1500cm^-1$\Rightarrow$ peak belongs to aromatic C-C bond strtching.

From above observation, compound must be
