A carbon atom has 4 valence electrons, so two together may have a single, double, or triple bond.
Ethene (C2H4) has 2 bonds between the 2 carbon atoms and each carbon atom shares 2 electrons from 2 Hydrogen atoms.
Bonds between two (adjacent) C atoms.
Ethane has nonpolar covalent bonds. These bonds are formed between the carbon and hydrogen atoms in ethane, where the electrons are shared evenly between the atoms.

When two carbon atoms are linked by a triple bond, one will be a sigma bond (formed by the 2px-px overlap of the two carbon atoms) whereas the other two will be pi bonds (formed by the 2py-py overlap and 2pz-pz overlap of the two carbon atoms).
There are four covalent bonds in Carbon Tetrachloride. The bonds sit between C and Cl.
Ethene (C2H4) has 2 bonds between the 2 carbon atoms and each carbon atom shares 2 electrons from 2 Hydrogen atoms.
There are 3 pi bonds present in benzene (C6H6), which is a cyclic compound with alternating single and double bonds between carbon atoms.
There are two pi bonds present in CH3NO2. One pi bond is between the carbon and nitrogen atoms, and the other pi bond is between the nitrogen and oxygen atoms.
Bonds between two (adjacent) C atoms.
There are three covalent bonds between carbon atoms in acetylene, as acetylene has a triple bond between the two carbon atoms.

Only sigma bonds are present in ethane. There is one carbon-carbon sigma bond and six carbon-hydrogen sigma bonds in C2H6.
Lactic acid has two carbon atoms, four hydrogen atoms, and three oxygen atoms. It forms four covalent bonds between the carbon atoms and the oxygen atoms, and six covalent bonds between the carbon and hydrogen atoms. Therefore, lactic acid has a total of 10 covalent bonds.
There are 2 sigma bonds present in CH3OH. One sigma bond is between the carbon atom and each of the three hydrogen atoms (C-H bonds), and the second sigma bond is between the carbon atom and the oxygen atom (C-O bond).
Water (H2O) - formed by covalent bonds between hydrogen and oxygen atoms. Methane (CH4) - composed of covalent bonds between carbon and hydrogen atoms. Carbon dioxide (CO2) - consists of covalent bonds between carbon and oxygen atoms.
Silicon carbide contains both ionic and covalent bonds. The silicon and carbon atoms form covalent bonds, while the silicon and carbon atoms are also bonded to each other through ionic bonds due to the electronegativity difference between the two elements.
