Knowing bond types

Postby salvadorramos3k » Fri Oct 25, 2019 8:46 pm

How can I tell whether a bond is going to be a single, double, or triple bond? I can usually tell when a bond is going to be a single, but sometimes when I think that a single bond makes sense, it has to be a double bond or something. Thank you :)

Overall, it depends on the element that is being bonded with. For example, hydrogen can only form one bond while other atoms such as carbon and oxygen can form four bonds (want to fill valence shell to an octet). However, elements like Sulfur, Phosphorus, and Chloride can accommodate more than 8 valence electrons and instead this structure depends on the formal charge of atoms (will prefer most stable structure with formal charge of 0).

The acronym HONC helps me with bonds. Hydrogen (H) prefers 1 bond, Oxygen (O) prefers 2 bonds, Nitrogen (N) prefers 3 bonds, and Carbon (C) prefers 4 bonds.
