Problem

Write an equation for the Brønsted–Lowry acid–base reaction that occurs when each of the following acids react with water. Show all unshared electron pairs and formal charges, and use curved arrows to track electron movement.

(a) H–C≡N

Solution

We’re being asked to provide the product and mechanism for the reaction of HCN with H2O.


Recall that a Bronsted-Lowry acid is a proton (H+) donor while a Bronsted-Lowry base is a proton acceptor. Also, recall that H2O can act as either an acid or a base.
