QUESTION 10 + CI HAS products Et, For this reaction with H2S, which of the following statements are true? The sulfur nucleophile will add to the ester functional group. This will be a substitution reaction, with -Cl acting as a leaving group, This will be a fast reaction at room temperature. This reaction is an example of nucleophilic acyl stubstition (up-down-out mechanism). There will be no reaction under normal conditions.

In the case of conjugated dienes, that is dienes that are separated by one sigma bond, the carbocation that is formed is stabilized additionally by resonance. Addition of the nucleophile to the carbocation intermediate can therefore...
