Question

In the following reaction sequence, the major product \(Q\) is:

Hint:

In such sequences, follow the functional group transformations step by step to identify the final product.

Answer 1

1. L-Glucose reacts with \(HI\) at high temperature to form \(n\)-hexane (\(CH_3-(CH_2)_4-CH_3\)). 2. \(n\)-hexane undergoes aromatization using \(Cr_2O_3\) at \(775 \, \text{K}\) to form benzene. 3. Benzene reacts with excess chlorine in the presence of UV light to form benzene hexachloride (\(C_6H_6Cl_6\)). Thus, the major product \(Q\) is benzene hexachloride (BHC).
