It could be a single bond (as in alkanes) or a double bond (as in alkenes) or even a triple bond (as in alkynes).
That one bond
Hydrogen form a covalent bond with carbon.
No it is not. Carbon is a covalent bond.
a molecular bond will be formed as both, carbon and bromine are non metals
carbon and oxygen
Carbon and Chlorine form polarized covalent bonds
You can form a C-C which is a single bond carbon and you can form a C equals C which is a double bond carbon. But if you were to form a triple C bond then the remaining 2 electrons that are located on the other side of the triple bond cannot form a bonding pair.
A double carbon bond is a covalent bond. Also carbon atoms can form double bonds. Carbon shares electrons with other atoms.
Carbon and oxygen typically form a covalent bond when they bond together. This type of bond involves the sharing of electrons between the two atoms, resulting in a strong bond.
Obviously carbon dioxide and oxygen cannot be combined by just sticking them in a bottle together, that would not chemically combing the atoms and create a compound. You would need to chemicaly combine them, the easiest way to heat them together.
Cl and F form ionic bond when they combine with metals and form covalent bond when combined with non-metals.
No. Water is a compound of oxygen and hydrogen. Carbon and oxygen will combined to form carbon dioxide or carbon monoxide.
