Short Answer

Expert verified

Answer

The structure of C4H8O is,

Step by step solution

01

Step-by-Step SolutionStep 1: 1H  NMR spectrum

1H NMR spectrum describes the types of proton present in the compound by looking at the chemical shift values. The different functional groups exhibits different chemical shifts values.

02

The structure of cyclic ether with formula C4H8O

From the given 1H NMR spectrum of cyclic ether with chemical formula C4H8O, the following observation is done as,

The chemical shift at 1.0 is forCH3 (a) (3H).

The chemical shift at 1.5 is for CH2 (b) (2H).

The chemical shift at 2.5 is for CH (d) (1H).

The chemical shift at 2.7 is for CH (e) (1H).

The chemical shift at 2.9 is for CH (c) (1H).

Thus, the structure of cyclic ether is,
