Question

The vigorous oxidation of pentan-2-one with concentrated $HNO_3$ yields a mixture of two distinct carboxylic acids. Assuming the major cleavage pathway strictly follows Popoff's rule, what is the exact molecular mass (in g/mol) of the carboxylic acid fragment that retains the original carbonyl carbon?

Prashant Kotian · Accepted Answer

Correct answer: 60. Pentan-2-one is . Popoff's rule dictates the carbonyl group () stays with the smaller alkyl group (). The fragment retaining the carbonyl carbon becomes Acetic acid (). The molar mass of acetic acid is g/mol.
