# 2.18 When we write arrow-pushing mechanlsms Involving proton transfer, It Is often difficultto keep track of aclds and bases. In general, when we wrte arrow-pushing mechanlsms that occur under ackdkc conditions, It Is best to represent the add and conjugate base as H-A and A-, respectively. Conversely, for mechanisms that occur under basic conditions, It Is best to represent the base and conjugate acld as Band B-H. For reactions that occur under neutral conditions, you can choose elther H-A/A or B:/B-H A Suggest a plauslble arrow-pushing mechanlsm for the following reaction, using H-A as the acld and A-as the conugate base 0 0 OCHs100C Suggest a plausible arrow-pushing mechanism for the following reaction, using B: as the base and +B-Has the conjugate acd B 25 C
