Which of the following compounds has the shortest C−−C bond length?Select answer from the options belowEthane (C2H6)Ethylene (C2H4)Acetylene (C2H2)
Question
Which of the following compounds has the shortest C−−C bond length?
Select answer from the options below:
- Ethane (C2H6)
- Ethylene (C2H4)
- Acetylene (C2H2)
Solution
The bond length in a molecule is determined by the type of bond between the atoms. There are three types of bonds: single, double, and triple. A single bond is the longest, a double bond is shorter, and a triple bond is the shortest.
- Ethane (C2H6) has a single bond between the carbon atoms.
- Ethylene (C2H4) has a double bond between the carbon atoms.
- Acetylene (C2H2) has a triple bond between the carbon atoms.
Therefore, Acetylene (C2H2) has the shortest C-C bond length.
