A. draw the structure of the tetrahedral intermediate initially formed in the reaction shown. you do not have to consider stereo
chemistry. do not include counter-ions,
e.g., na+, i-, in your answer. in cases where there is more than one answer, just draw one. move clear erase undo redo increase scale decrease scale copy paste set label more labels attributes more attributes single bond recessed bond protruding bond double bond other bond more bonds cyclohexane ring benzene ring other ring more rings bracket
b. draw the structures of the final acyl transfer products obtained.

1 answer:
The reaction is shown below, Acid protonates the carbonyl oxygen and makes the carbonyl carbon more electrophilic. Water attacks on activated carbonyl group and forms a tetrahedral intermediate.
Intermediate:
Structure of Intermediate is shown both in 2-D and 3-D (below attached).
Carbonyl group is regenerated with the elimination of ethanol.
Reaction is as below, The final product is carboxylic acid.

Answer:- D.
Explanations:- In chemical equations, (aq) stands for aqueous, (l) stands for liquid, (g) stands for gas and (s) stands for solid. In double replacement reactions, (aq) means soluble and (s) means insoluble that is precipitate.
Looking at all the equations, it is only the last equation that has a solid product and so this is the only precipitation reaction. A precipitate for Iron(II)carbonate is formed in it.
