Question

The mass spectrum of a certain molecule is shown below. Using the information provided in this mass spectrum, indicate which of the molecular formula shown below arc possible for this molecule (put OK in the box). For those that are NOT possible, provide a short explanation why they can be ruled out. An example has been done for you. The IR spectrum for the molecule in part a is shown below. Given this spectrum, only one of the molecular formulas shown in part a is possible. What is the molecular formula, and explain how you know.

Explanation / Answer

2a) In this spectrum molecular ion peak is 107

Also seems to be a base peak

Here the answar is C6H5NO

It obey Nitrogen rule.

Remaininmg compounds molecular weight are different from 107. And not obey nitrogen rule.

2b) Benzoic acid
