Question

How many signals would you expect to find in the 1h nmr spectrum of ch3och2ch2och3?

a) 1
b) 2
c) 3
d) 4

Answer 1

In a 1H NMR spectrum of CH3OCH2CH2OCH3, you would expect to find 3 distinct signals corresponding to the three unique hydrogen environments within the molecule.

Step-by-step explanation:

The molecule CH3OCH2CH2OCH3 would be expected to show a specific number of unique hydrogen environments in a 1H NMR (Proton NMR) spectrum. This organic molecule, commonly known as diethyl ether, would have a total of three distinct sets of hydrogen atoms. These include the hydrogen atoms in the methyl group (CH3), the methylene groups next to the oxygen atoms (OCH2), and the central methylene group (CH2). Each of these environments would give rise to a separate signal in the NMR spectrum. Therefore, the expected number of signals in the 1H NMR spectrum would be 3, which corresponds to option C.
