In ethane, C2H6, ethene (ethylene), C2H4, and ethine (acetylene), C2H2, there are direct carbon-carbon bonds. Which one is the shortest? a. The carbon-carbon bond in ethane's the longest!)
b. The carbon-carbon bond in ethene is the longest
c. The carbon-carbon bond in ethyne is the longest.
d. All of the carbon-carbon bonds have the same length.

a. The carbon-carbon bond in ethane's the longest!)

Explanation:

Ethane is a chemical compound that is organic in nature. Its chemical formula is . It has two carbon atoms and six of hydrogen atoms that is connected to the carbon atoms.

Ethane is odorless and colorless at the standard temperature and standard pressure.

The carbon to carbon atoms in ethane is connected by a single bond.

The length of single carbon-carbon bond is greater than carbon-carbon double bond and triple bond.

Thus, carbon-carbon bond length in ethane is the longest.
