Question

For the given reactions ,the name of the reaction which isn't correctly matched is :

• A. $\text{n-butane}\underset{\Delta }{\overset{AlC{l}_3+HCl}{\to }}\text{2-methyl propane}:\text{Isomerisation}$
• B. $C_6{H}_{14}\stackrel{773K}{⟶}{C}_4{H}_8+C_2{H}_6:\text{Pyrolysis}$
• C. $C{H}_4+2O_2\stackrel{\Delta }{⟶}C{O}_2+2H_{2}O:\text{Controlled oxidation}$
• D. $\left(C{H}_3{)}_{3}CH\stackrel{Kmn{O}_4}{\to }\right(C{H}_3{)}_{3}C-OH:\text{Controlled oxidation}$

Answer 1

The correct option is C $C{H}_4+2O_2\stackrel{\Delta }{⟶}C{O}_2+2H_{2}O:\text{Controlled oxidation}$

(A) : Isomerisation is a reaction hwere one organic compound (n - butane) converts to another compound (2 - methyl propane) with the same molecular mass but different structures
(B): Pyrolysis is breaking down of a larger hydrocarbon (Hexane) through the application of heat to simpler hydrocarbons (Butane and Ethane) in absence of oxygen.
(C) $C{H}_4+2O_2\stackrel{\Delta }{⟶}C{O}_2+2H_{2}O$
The above reaction is complete oxidation or combustion of alkanes.

Hence, (C) is not correctly named.
(D):$\left(C{H}_3{)}_{3}CH\stackrel{Kmn{O}_4}{\to }\right(C{H}_3{)}_{3}C-OH:\text{Controlled oxidation}$
This is controlled oxidation of alkane (isobutane) with $Kmn{O}_4$ to form 2-Methylpropan-2-ol
