NEET levelSingle correct optionDifficulty 1 of 3o2007

But-1-ene is treated with $Hg (OAc) X_{2}$ in $THF / H X_{2} O$ followed by $NaBH X_{4}$ . The product is

Abutan-2-ol
B2-methylpropan-2-ol
Cbutan-1-ol
Dbutane-1,2-diol

Answer: A

Oxymercuration-demercuration is a Markovnikov hydration. Water attacks the more substituted carbon (C-2) of the mercurinium ion, and

NaBH X_{4}

replaces Hg by H. The product is butan-2-ol.
