Concept explainers
(a)
Interpretation: The curved arrows are to be used to show the movement of electrons in the given equation.
Concept introduction: There are generally two types of arrows ‘reaction arrows’ and ‘electron arrows’. A reaction arrow gives the information regarding the progress of the reaction. An electronegative element in the reaction attracts electron toward it.
Half headed arrows are used to show the flow of single electrons, while the full headed arrow shows the movement of electron pairs.
