Answer:
In carbon containing compounds, carbon usually forms four bonds, nitrogen usually forms three bonds, oxygen usually forms two bonds, and hydrogen only forms one bond.
Step-by-step explanation:
In organic compounds in which carbon is present, the number of bonds formed depend on the number of electrons available for each chemical element. In the case of Carbon, it is 4. Nitrogen is 3. Oxygen is 2. Hydrogen is 1. In other types of compounds, it is possible to see different types of bonds.
