JEE MAIN - Chemistry (2021 - 27th July Morning Shift - No. 7)
Presence of which reagent will affect the reversibility of the following reaction, and change it to a irreversible reaction :
CH4 + I2 $$\mathrel{\mathop{\kern0pt\rightleftharpoons} \limits_{{\mathop{\rm Re}\nolimits} versible}^{hv}} $$ CH3 $$-$$ I + HI
CH4 + I2 $$\mathrel{\mathop{\kern0pt\rightleftharpoons} \limits_{{\mathop{\rm Re}\nolimits} versible}^{hv}} $$ CH3 $$-$$ I + HI
HOCl
dilute HNO2
Liquid NH3
Concentrated HIO3
Explanation
Iodination of alkane is reversible reaction. It can be irreversible in the presence of strong oxidising agent like conc. HNO3 or conc. HIO3.
