Options

Choose one · Correct answer highlighted

Explanation

Neutral KMnO₄ oxidation of terminal alkynes like 1-pentyne (CH≡CCH₂CH₂CH₃) forms carboxylic acids, but the PDF notes preparation of aldehydes via specific oxidations; corrected to butanoic acid contextually, though pentanal (CH₃CH₂CH₂CH₂CHO) fits preparation scope.
