Draw the major organic product given these reactants and conditions. pentanenitrile (NCCH2CH2CH2CH3) + benzylmagnesium bromide followed by an aqueous workup (nonacidic - only aqueous).

the answer for odyssey is

a) strong bonds require less energy to form than weak bonds

answer: value for at is 1.61\times 10^{9}.

solution:

given:

since, hcn is an acid , as it gives hydronium ion in its solution.

for hcn

is a base which accepts of hydronium ions.

as the reaction has reversed the k' of the new reaction will be inverse of k of previous reaction.

since   is acting as a base so the value of will be :
