Identify the atoms involved in the formyl group: carbon (C), hydrogen (H), and oxygen (O). The formyl group is a functional group derived from an aldehyde, where carbon is bonded to both hydrogen and oxygen.
Recall the typical bonding patterns: carbon usually forms four bonds, oxygen typically forms two bonds (often with lone pairs), and hydrogen forms one bond.
Consider the possible bonds between the atoms. The carbon atom should be bonded to the hydrogen atom with a single bond, and to the oxygen atom with a double bond to satisfy the octet rule for carbon and oxygen.
Draw the Lewis structure showing carbon double-bonded to oxygen (C=O) and single-bonded to hydrogen (C-H). This arrangement ensures that carbon has four bonds total, oxygen has two bonds (plus lone pairs), and hydrogen has one bond.
Verify that the structure satisfies the octet rule for carbon and oxygen, and that the formal charges are minimized, confirming that the correct Lewis structure for the formyl group is H-C=O.
