Question

Draw curved arrows to illustrate the following Bronsted acid-base reactions.

Draw curved arrows to illustrate the following Br?nsted acid?base reactions.

Answer 1

Concepts and reason

Bronsted Acid-Base Theory:

Brønsted Acid: An acid is a hydrogen atom containing substances that donate a proton.

Brønsted Base: A base is any substance that accepts a proton.

Arrow Pushing in Chemistry:

Arrow pushing is a technique to indicate the movement of electrons during chemical reactions.

Fundamentals

Acids are proton donors. For example, .

Bases are proton acceptors. For example, .

Arrow Pushing Rules:

Arrows are used to represent the flow of electrons.

Curved arrow (double head) for a pair of electrons: Indicate movement of an electron pair.

Curved arrow (single head) for a single electron: Indicate movement of an electron.

Arrows always begin at an electron source and end at an electron sink.

Ans:

Hence, the curved arrows for forward and reverse reaction are as follows:
