Reduction of 4-methylpentan-2-one to the corresponding alcohol results in the molecule A - Scottish Highers Chemistry - Question 22 - 2023

This implies a specific mass loss during the reduction. In organic chemistry, the reduction of ketones does not typically result in this specific weight change, making this option also incorrect.

A loss of 16 g indicates a significant reduction in molecular mass. However, reduction does not generally entail such drastic mass loss; hence, this option is also incorrect.

Reduction primarily involves the conversion of a ketone to an alcohol through the addition of hydrogen. The overall molecular weight remains largely unchanged apart from the addition of hydrogen atoms, making this option correct.
