Question

For the reaction:

C(CH3)3I + Cl− → C(CH3)3Cl + I−

What is the activation barrier for the SN2 reaction mechanism, in units of kcal/mol? Provide your answer to the nearest 0.1 kcal/mol.

Answer 1

Hey there!

For SN1 mechanism; the activation barrier is the C-I bond energy which is broken in the first step of the reaction.

The activation barrier is : 56 kcal/ mol = 5.6 kcal/ mole ( nearest 0.1)
