Question

A sample of allyl chloride contained a significant amount of an impurity. The impurity was isolated using distillation technique and a ¹³C-NMR spectrum of the impurity was obtained.

13C NMR spectrum of C3H6O showing peaks at 63, 118, and 134 ppm.

If the molecular formula of the impurity is C₃H₆O:
(i) Give a plausible structure for the impurity.
(ii) Assign all peaks in the ¹³C-NMR spectrum of the impurity.
(iii) Explain how the impurity arose in the sample of allyl chloride.

Accepted Answer

Proposed structure of C3H6O with NMR peak assignments and hydrolysis reaction of allyl chloride.
