Acyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. CH₂OH

Rank the following esters in order of decreasing reactivity in the first slow step of a nucleophilic acyl substitution reaction (formation of the tetrahedral intermediate):Rank the same esters in order of decreasing reactivity in the second slow step of a nucleophilic acyl substitution reaction (collapse of the tetrahedral intermediate).

Can you draw the mechanism for the synthesis of cyclohexene from cyclohexanol through an acid-catalyzed dehydration reaction. Where  Phosphoric acid donates a proton ((H^+)) to the hydroxyl group of cyclohexanol, forming a protonated cyclohexanol intermediate.    •    The protonated cyclohexanol undergoes dehydration, leading to the removal of a water molecule and the formation of cyclohexene.    •    The released proton combines with water to form hydronium ion (H3O+), regenerating the catalyst. The mechanism should illustrate the acid-catalyzed dehydration process, where phosphoric acid facilitates the removal of water from cyclohexanol, resulting in the formation of cyclohexene.
