Draw the Lewis dot structure for {eq}H_2CO {/eq}.


Draw the Lewis dot structure for {eq}H_2CO {/eq}.

Lewis Structure:

A Lewis structure describes the arrangement of all bonding and non-bonding valence electrons present in a covalent molecule or ion containing two or more connected atoms. The shared valence electron pairs (bonding electrons) are written as one or more connecting lines between a pair of atoms. They can also be written as one or more pairs of dots. In either form of a Lewis structure the non-bonding electrons present on atoms are always written as dots. In most cases a Lewis structure will also contain the geometry of the molecule or ion.
