Question

Assign structures to compounds with the following ¹H NMR spectra:

(a)C₅H₁₀O₂

IR:1735 ${\mathrm{cm}}^{-1}$

(b)C₁₁H₁₂O₂

IR:1710 ${\mathrm{cm}}^{-1}$ 

Step-by-Step Solution

Answer

The structure of the compound using ¹H NMR spectra can be drawn.The structure of the compound using ¹H NMR spectra can be drawn.

Step 1: Drawing the structure for C 5 H 10 O 2 with IR=1735 cm -1

The structure indicates carboxylic acid.

Step 2: Drawing the structure for C 11 H 12 O 2 with IR=1710 cm -1

The structure indicates the structured carboxylic acid.
