The molecular mass of an organic compound which contains only one nitrogen atom can be

Options

A. 73
B. 76
C. 146
D. 152

Answer

A

Explanation

All compounds containing an odd number of `N` atoms (i.e. 1, 3, 4,…….etc) have odd masses and those which contain even number of `N` atoms (i.e., `2,4,5` ……etc.) have even mases. This is called nitrogen rule. Thus, option (a) is correct.
