One mole of an organic compound requires 0.5 moles of oxygen to produce a carbox

One mole of an organic compound requires 0.5 moles of oxygen to produce a carboxylic acid. The compound may be:

  • A. alcohol
  • B. ether
  • C. ketone
  • D. aldehyde

Step-by-step solution

The oxidation of an aldehyde to a carboxylic acid requires half a mole of O2 per mole of aldehyde: R-CHO + 0.5 O2 → R-COOH. Alcohols require 1 mole of O2, ethers do not directly yield carboxylic acids, and ketones typically require more than 0.5 moles or undergo cleavage.
