In the reaction, Cl2 + CH4 xrightarrowhv CH3Cl + HCl presence of a small amount of oxygen

Question

In the reaction, Cl2 + CH4 xrightarrowhv CH3Cl + HCl presence of a small amount of oxygen (A) increases the rate of reaction for a brief period of time (B) decreases the rate of reaction for a brief period of time (C) does not affect the rate of reaction (D) completely stops the reaction

Tardigrade Admin · Accepted Answer

Halogenation of alkanes follows free radical mechanism and presence of a small amount of oxygen can slow down the reaction for a period of time depending upon the amount of oxygen. Oxygen reacts with methyl free radical to form less reactive free radical and acts as an inhibitor.
