The two reactions that follow involve nucleophilic substitution at an acyl carbon. For each reaction, show the electrophile and the nucleophile in the key bond- forming step, the corresponding tetrahedral addition intermediate, and the leaving group in the bond-breaking step. Write a general mechanistic scheme (use curved arrows to show bond-making and bond-breaking processes) for these reactions, keeping in mind that acid- and base-catalyzed processes will differ in their timing of proton transfers. 00 PhCOCPh+ C₂H5OH 00 PhCOCPh+ 2 CH3NH H₂SO4 cat.

The conversion of alcohols into alkyl halides by reaction with hydrogen halides is an example of a Nucleophilic Substitution Reaction. This kind of reaction can proceed by two different mechanisms depending on the structure of alcohol substrates used. Generally, primary alcohols are substituted via SN2 mechanism, while secondary and tertiary alcohols undergo SN1 mechanism. Consider the following reaction given in the picture below and the questions in the picture too.
