One or More than One Options Correct TypeDirection (Q. Nos. 8-12) This...
To perform free radical chlorination of propane, we need a reagent that can generate chlorine radicals, which are highly reactive and can abstract a hydrogen atom from propane to form a chlorinated product.
Options:
a) SOCI2 (Thionyl chloride)
b) SO2Cl2 (Sulfuryl chloride)
c) Cl2/hv (Chlorine in the presence of light)
d) PCI3 (Phosphorus trichloride)
Explanation:
b) SO2Cl2 (Sulfuryl chloride) is a reagent that can bring about free radical chlorination of propane. It can be used as a source of chlorine radicals in the presence of heat or light. When heated or exposed to light, SO2Cl2 undergoes homolytic cleavage to form chlorine radicals:
SO2Cl2 → 2SOCl•
These chlorine radicals can then abstract a hydrogen atom from propane, leading to the formation of a chlorinated product:
CH3CH2CH3 + Cl• → CH3CH2CH2• + HCl
CH3CH2CH2• + Cl2 → CH3CH2CH2Cl + Cl•
Thus, SO2Cl2 can be used as a reagent for free radical chlorination of propane.
c) Cl2/hv (Chlorine in the presence of light) is also a suitable reagent for free radical chlorination of propane. When chlorine is exposed to light, it undergoes homolytic cleavage to form chlorine radicals:
Cl2 → 2Cl•
These chlorine radicals can then abstract a hydrogen atom from propane, resulting in the formation of a chlorinated product:
CH3CH2CH3 + Cl• → CH3CH2CH2• + HCl
CH3CH2CH2• + Cl2 → CH3CH2CH2Cl + Cl•
Thus, Cl2/hv can bring about free radical chlorination of propane.
In summary, options b) (Sulfuryl chloride) and c) (Chlorine in the presence of light) are the correct choices for the reagents that can bring about free radical chlorination of propane.
