Identify compound X in the following sequence of reactions: CH3 → CHO → CH2Cl → CHCl2 Cl2/hν → H2O → 373K

1. CH3 (a)
2. CHO (b)
3. CH2Cl (c)
4. CHCl2 (d)

Correct answer: CHCl2 (d)

Solution

The sequence involves the chlorination of methane (CH3) under UV light to form CH2Cl and then CHCl2. The final product is CHCl2 after two chlorination steps.
