Briefly describe the infrared (IR) and nuclear magnetic resonance (both 1H- and 13C-NMR) spectra, and what these data mean to you. of 2,6-dimethylphenyl chloroacetate
Added by Katrina F.
Step 1
- For 2,6-dimethylphenyl chloroacetate, you would expect to see characteristic peaks: - A strong peak around 1730-1750 cm⁻¹ indicating the presence of a carbonyl (C=O) group from the ester functional group. - Peaks in the region of 1000-1300 cm⁻¹ corresponding Show more…

Identify each compound from its spectral data. a. Molecular $\mathrm{C}_{3} \mathrm{H}_{5} \mathrm{ClO}_{2}$ formula: $$ I R: 3500-2500 \mathrm{~cm}-1,1714 \mathrm{~cm}^{-1} $$ 1H NMR data: 2.87 (triplet, $2 \mathrm{H}$ ), 3.76 (triplet, $2 \mathrm{H}$ ), and 11.8 (singlet, 1 H) ppm b. Molecular $\mathrm{C}_{8} \mathrm{H}_{8} \mathrm{O}_{3}$ $$ \text { IR: } 3500-2500 \mathrm{~cm}-1,1710 \mathrm{~cm}^{-1} $$ 1H NMR data: 4.7 (singlet, $2 \mathrm{H}$ ), $6.9-7.3$ (multiplet, $5 \mathrm{H}$ ), and 11.3 (singlet, 1 H) ppm c. Molecular $\mathrm{C}_{4} \mathrm{H}_{7} \mathrm{~N}$ formula: $$ \text { IR: } 2250 \mathrm{~cm}^{-1} $$ 1H NMR data: 1.08 (triplet, $3 \mathrm{H}$ ), 1.70 (multiplet, $2 \mathrm{H}$ ), and 2.34 (triplet, $2 \mathrm{H}$ ) ppm
Propose a structure that is consistent with the set of 1H NMR data. IR data is also provided.
