Answer 1

Spectrum 1: Spectrum 1 shows characteristic signals for aliphatic C-H stretching (2900cm-1 to 3000 cm-1), carbonyl stretching (~1725 cm-1), no aldehyde C-H stretching, no C-O stretching. Thus, most probable functional group is ketone and most probable structure is (A) Pentan-3-one.

pentan-3-one

----------------------------------------------------------------------------------------------------------------------------------------------------

Spectrum 2: Spectrum 2 shows characteristic signals for aliphatic and alkene C-H stretching (2900 cm-1 to 3100 cm-1). Thus, most probable compound is (D) Cycloheptene

cycloheptene

----------------------------------------------------------------------------------------------------------------------------------------------------

Spectrum 3 : Spectrum 3 shows characteristic signals for aliphatic C-H stretching (~2900cm-1-3000cm-1), ester (~1745 cm-1), C-O strectching (~1050cm-1 and 1220 cm-1). Thus, most probable compound is (E) Ethyl acetate

ethyl acetate

----------------------------------------------------------------------------------------------------------------------------------------------------

Spectrum 4: Spectrum 4 shows characteristic signals for aliphatic and aromatic C-H stretching (2900 cm-1– 3100 cm-1), ester (~1745 cm-1), C-O strectching (~1050cm-1 and 1220 cm-1). Thus, most probable compound is (I) Methyl benzoate

methyl benzoate

----------------------------------------------------------------------------------------------------------------------------------------------------

Spectrum 5 : Spectrum 5 shows characteristic signals for hydroxyl group (3300cm-1 – 3600 cm-1), aliphatic C-H stretching (2900cm-1 – 3000 cm-1). Thus, most probable compound is (H) 2-methylcyclohexan-1-ol

-ОН 2-methylcyclohexan-1-ol
