Ethyne, C2H2, has a 5 covalent bond between the two carbon atoms.
ethane C2H6, has a 6 covalent bond
Explanation:
Ethyne are covalent compounds since these compound involve bonding between two non metals. In H2S H 2 S , the compound is formed when sulfur shares two of its valence electrons with two hydrogen atoms through a covalent bond
Ethane
6 bonds between C−H and one is between C−C. The six hydrogen atoms will each share their 1 electron with carbon to form six carbon-hydrogen covalent bonds. The two carbon atoms will each share their 1 electron to form one carbon-carbon covalent bond
