Question

Difference between ethene and ethane gas

Answer 1

Both ethane and ethene are hydrocarbons having carbon and hydrogen atoms. Hydrocarbons can be further categorized into groups depending on their functional groups. Alkanes and alkenes are the two basic categories in organic chemistry. Alkanes have single bonds only, and they are saturated compounds. Alkenes are hydrocarbons with carbon- carbon double bonds. These are also known as olefins. The physical properties of alkenes are similar to the corresponding alkanes.

Ethane

Ethane is a simple aliphatic hydrocarbon molecule with C2H6 molecular formula. Ethane is said to be a hydrocarbon because it consists carbon and hydrogen atoms only. Ethane is also known to be an alkane because it does not have multiple bonds between carbon atoms. Further, ethane contains the maximum number of hydrogen atoms that a carbon atom can possess, making it a saturated alkane. Ethane is a colorless, odorless gas. The molecular weight of ethane is 30 g mol-1. Each carbon atom in ethane has a tetrahedral geometry. The H-C-H bond angle is 109o. The carbon atoms in ethane are sp3 hybridized. A sp3 hybridized orbital from each carbon atom overlaps to make the carbon-carbon sigma bond. The bond between carbon and hydrogen is also a sigma bond, but it is made up by overlapping a sp3 hybridized orbital of the 

Answer 2

Very easily ethane is an alkane and ethene is an alkene. Study organic chemistry more as you are asking this kinds of questions.
