For the following SNS_N reaction,

(CH3)3CCl+H2O⟶(CH3)3COH+HCl\left(\mathrm{CH}_3\right)_3 \mathrm{CCl}+\mathrm{H}_2 \mathrm{O} \longrightarrow\left(\mathrm{CH}_3\right)_3 \mathrm{COH}+\mathrm{HCl}

Rate-determining step is
View answer and explanation
Correct option: A
(CH3)3CCl⟶(CH3)3C++Cl−\left(\mathrm{CH}_3\right)_3 \mathrm{CCl} \longrightarrow\left(\mathrm{CH}_3\right)_3 \mathrm{C}^{+}+\mathrm{Cl}^{-}
Option A ((CH3)3CCl⟶(CH3)3C++Cl−\mathrm{CH}_3)_3 \mathrm{CCl} \longrightarrow(\mathrm{CH}_3)_3 \mathrm{C}^{+}+\mathrm{Cl}^{-}) is correct because the rate-determining step in an SN1 reaction is the formation of the carbocation.

If the reaction rate at a given temperature becomes slower then 1[A]2\frac{1}{{{{\left[ A \right]}^2}}} vs times are a straight line. Order of reaction is The rate constant (k′)\left( {k'} \right) of one of the reaction is found to be double that of the rate constant (k′′)\left( {k''} \right) of another reaction. Then the relationship between the corresponding activation energies of the two reaction (E′a  and  E′′a)\left( {{{E'}_a}\;\mathrm{and}\;{{E''}_a}} \right) can be represented as Acid hydrolysis of sucrose is a Order of radioactive disintegration reaction is Temperature coefficient of a reaction is 2.
