Name the reagent following reaction.
`{:(undersetunderset(" "CH_2OH)(|)oversetoverset(" "CHO)|(" "(CHOH)_4),to, underset"n-hexane"(CH_3-(--CH_2--)CH_3)):}`
Choose the correct option.

Options

A. `HF,Delta`
B. `HCl, Delta`
C. `HBr , Delta`
D. `HI, Delta`

Answer

D

Explanation

On prolonged t,eating with HI, glucose forms hexane, suggesting that all 6 carbon atoms are linked in straight chain.
