Question

Acid catalyzed hydrolysis of HOCH2CH2C(CH3)2CN forms compound A (C6H10O2). A shows a strong peak in its IR spectrum at 1770 cm−1 and the following signals in its 1 H NMR spectrum: 1.27 (singlet, 6 H), 2.12 (triplet, 2 H), and 4.26 (triplet, 2 H) ppm. Draw the structure for A and select the correct answers to complete a mechanism that accounts for its formation.

Answer 1

Answer:

3,3-dimethyldihydrofuran-2(3H)-one

Explanation:

The simulated spectrum of molecule => Figure 1

Mechanism=>Figure2

Answer 2

Answer:

From the given problem statement we need to hydrolyses HOCH2CH2C(CH3)2CN structure that forms (C6H10O2)

Peak of IR spectrum=1770 cm^-1

This structure for A involves 6 carbon atoms,four hydrogen atoms and 6 oxygen atoms for a complete reaction to occur.
