CH3CH2I reacts more rapidly with strong base in comparison to CD3CH2I. The elimination of HI (or DI) in presence of strong base shows E2 elimination. The rate determining step involves the breaking up of C-H (or C-D) bond. The C-D bond being stronger than C-H and thus elimination is faster in case of CH3CH2l.
