What hydrocarbons that contain a six-membered ring will have a molecular ion peak at m/z = 112?

Short Answer

Expert verified

Possible hydrocarbons are:

Step by step solution

01

Mass spectrometry

It is defined as the spectrometry technique which is used to identify the molecular mass of the compound by the molecular ion peak and the mass to charge ratio of the compound.

02

Identification of the compound

As the mass to charge ratio is 112 then we can find the number of carbons dividing by 13 so the possible number of carbon is 112/13 is 8 and the number of carbon atoms is also 8.

As the possible number of hydrogen is equal to the sum of the number of carbon and the number of remaining hydrogen atoms. So the number of hydrogen is 8+8=16.

So the molecular formula isC8H16

03

Identification of the compound from molecular formula

As now we get the molecular formula we can find the degree of unsaturation which is 1 as given having one six-membered ring so the possible structure of C8H16are shown below:
