# What is the maximum number of covalent bonds a carbon atom can form with other atoms?

And so carbon is tetravalent...(or more properly quadrivalent..) Ad organic chemistry provides a wealth of examples where carbon has the FOUR COVALENT bonds to hydrogen, oxygen, nitrogen, or other atoms....or to carbon itself...and unsaturated bonding, i.e. $C = C$, and $C \equiv C$ functions, is also a REAL possibility....
