Question

For the following reaction
$(C{H}_3{)}_{3}CCI+H_{2}O\to (C{H}_3{)}_{3}COH+HCl,$
$\left(\frac{dx}{dt}\right)=k\left[CH\_3\right)\_3CCI]$ hence rate determining step can be :

• A. $(C{H}_3{)}_{3}CCl\to (C{H}_3{)}_{3}C+C{l}^{-}$
• B. $(C{H}_3{)}_{3}CCl+H_{2}O\to (C{H}_3{)}_{3}COH+HCl$
• C. $(C{H}_3{)}_{3}C+H_{2}O\to (C{H}_3{)}_{3}COH+H^{+}$
• D. $H^{+}+C{I}^{-}\to HCl$

Answer 1

The correct option is A $(C{H}_3{)}_{3}CCl\to (C{H}_3{)}_{3}C+C{l}^{-}$

Here since rate equation depends only on $(C{H}_3{)}_{3}CCl$ hence rate determining step also containing only this as a reactant. Hence option A is correct
