Arrange Ethane, Ethene and Ethyne in decreasing order of the bond strength between the two carbon atoms in the given hydrocarbons.
Open in App
Solution
The correct option is D Ethyne > Ethene > Ethane
As the number of shared electrons increases, the bond strength increases.
In a triple bond, a total of 6 electrons are shared. In a double bond, 4 electrons are shared and in a single bond, only 2 electrons are shared. Thus, the order is as follows:
Ethyne > Ethene > Ethane.
Ethyne > Ethene > Ethane
As the number of shared electrons increases, the bond strength increases.
In a triple bond, a total of 6 electrons are shared. In a double bond, 4 electrons are shared and in a single bond, only 2 electrons are shared. Thus, the order is as follows:
Ethyne > Ethene > Ethane.
