QUESTION 11 Which one is a wrong statement about the intermediate of nucleophilic acyl subsitution? The intermediate is a result of forming a new T bond. The step in mechanism after intermediate formation is reforming carbonyl group and loss of leaving group. O it is a tetrahedral intermediate. In the intermediate, O from carbonyl group is negatively charged. After nucleophilic attack step, the attacked carbon in the intermediate has sp hybridization. O O O
