When D-threose is treated with NaBH₄/H₂O, it forms _______.

Question

Quizplus · Accepted Answer

NaBH₄/H₂O is a reducing agent that can be used to reduce ketones and aldehydes to alcohols. D-threose is a ketose, which can be converted to an alditol through a reduction reaction. When a ketone or aldehyde is reduced with a chiral reducing agent like NaBH₄/H₂O, the resulting alcohol will be optically active due to the transfer of chirality from the reducing agent to the substrate. Therefore, the best answer is C, an optically active alditol. A racemic mixture of alditols (A), a meso alditol (B), and an optically active aldonic acid (D) are not expected products from the reduction of D-threose with NaBH₄/H₂O.
