A chemical structure of a molecule includes the arrangement of atoms and the chemical bonds that hold the atoms together. Why there is a double bond formed between the carbon and oxygen atoms in CH2O? When there are lone pairs, you need to look at the structure and recognize the names and bond angles. Note, the lone pair takes up more space than the bonding pair, so the bond angle is less then the ideal 120o. 15 0 R >> /XObject << /Im1 18 0 R /Im2 20 0 R /Im3 22 0 R >> >> There are three common types of molecules that form these structures, molecules with two single bonds (BeH2), molecules with a two double bonds (CO2) and molecules with a single and triple bond (HCN).
