Question

Add curved arrows to the reactants in this reaction. A double-barbed curved arrow is used to represent the movement of a pair of electrons.

Answer 1

Concepts and reason

Movements of electrons in a chemical equation are denoted by curved arrows; curved arrow notation is used to determine and predict product species for an unfamiliar reaction.

Fundamentals

Significant features in curved arrow notation:

• For a curved arrow, the tail represents the atom from which the electrons originate.

• Head of the arrow represents, the destination to where the electrons are heading.

• The single barbed arrow represents the movement of a single electron.

• The double barbed arrow represents the movement of two electrons.

In the curved arrow notation, the electron movement starts from electron rich atom and heads toward electron poor atom.

Electron rich and electron poor species in the given reactant species are ${\bf{O}}$ and ${\bf{H}}$ respectively.
