Add curved arrows to the reactant of the reaction, a double barbed curved arrow is used to represent the movement of pair of electrons.
Plz include hydrogen atoms on non carbon atoms, and include non bonding electrons as well. Thnx  


It is actually a quiz question which I ggot in ym quiz, i tried an attempt putting an arrow from oxygen of hydroxide ion to the hydrogen of another reactant and then putting another arrow from the same hydrogen to it's nearest oxygen, I got this wrong. I think I did not put non bonding electrons which I dont even knw how to put.

In this question you have to show movement of electrons using arrow.Tip of the arrow indicates the direction of flow of the electrons and tail is on the atom from where electrons are moved.Like here H of the carboxylic acid
will give its electrons to O of the acid and O of the OH will give its electrons to H of the carboxylic acid .
