$\ce{C-H}$ bond and $\ce{C-D}$ bonds are not the same in energy. $\ce{C-D}$ bond is stronger. So breaking $\ce{C-D}$ bond is more difficult and slower than breaking $\ce{C-H}$ bond. I hope you know ...

If rate of SN1 is more does that automatically mean rate of SN2 is less, and vice versa?
4 votes

No. Example 1 - neopentyl halide: slow SN2 as it has considerable steric hindrance; slow SN1 as it is a primary carbon, so it does not form stable carbocation intermediate. Example 2 - benzyl halide: ...

The key thing to note here is that $E_\mathrm{cell} = E^\circ$ only when the ions involved are all in their standard states, i.e. concentrations of all ions is $\pu{1 M}$. But here we need to find $\...

I believe the mechanism should be somewhat like this (after the formation of carbocation) - It would account for the product shown, but I am not sure if it's correct. I feel it's more favourable for ...
