Per NCERT §9.4.3, addition of water to propyne under HgSO₄/H₂SO₄ gives mainly which product (Markovnikov)?
APropan-1-ol (primary)
BPropan-2-one (acetone)
CPropan-2-ol (secondary)
DPropanal (an aldehyde)
Answer & Solution
Correct answer: B. Propan-2-one (acetone)
NCERT §9.4.3: water adds Markovnikov; OH on more substituted carbon → enol tautomerises to ketone (acetone).
