Introduction to Proton Transfer

Most of the principles used to explain the acidity of compounds are also used to explain the reactivity and stability of organic compounds in general. Also, proton transfer reactions are often the first step in most organic reactions. For this reason, if we can thoroughly comprehend proton transfer, then we have a solid basis for understanding most organic reactions.

Draw the acid, conjugate acid, and electron flow arrows for the reaction below. 

Answer The missing acid is the conjugate base with a proton added on its most basic atom. The missing conjugate acid is the base with a proton added on its most basic atom. Note that charge has to balance, so the conjugate acid had to be positively charged.
