Difference between Ethene and Propene

Ethene and propene are both hydrocarbons belonging to the alkene family. They are unsaturated hydrocarbons with a double bond between carbon atoms. However, there are some differences between ethene and propene:

1. Chemical Formula: Ethene has the chemical formula C2H4, while propene has the chemical formula C3H6. This means that ethene has two carbon atoms and four hydrogen atoms, while propene has three carbon atoms and six hydrogen atoms.

2. Structure: Ethene has a linear structure, with the double bond between the two carbon atoms. Propene, on the other hand, has a branched structure, with the double bond between the second and third carbon atoms.

3. Physical Properties: Ethene is a colorless gas at room temperature and pressure, while propene is a colorless gas as well. However, propene has a slightly higher boiling point and density compared to ethene.

4. Uses: Ethene is primarily used in the production of plastics, such as polyethylene. It is also used as a fuel in welding and cutting operations. Propene is used in the production of various chemicals, including propylene oxide, acrylonitrile, and polypropylene.

Systematic Nomenclature for C4H10

The systematic nomenclature for C4H10 is butane. Butane is an alkane with four carbon atoms and ten hydrogen atoms. It exists in two isomeric forms: n-butane and isobutane.

1. n-Butane: n-Butane, also known as normal butane, has a straight-chain structure. It has the following structural formula: CH3-CH2-CH2-CH3. The prefix "n-" indicates that the carbon atoms are arranged in a straight chain.

2. Isobutane: Isobutane, also known as 2-methylpropane, has a branched structure. It has the following structural formula: (CH3)3CH. The prefix "iso-" indicates that the carbon atoms are arranged in a branched structure.

Both n-butane and isobutane are commonly used as fuel gases, such as in lighters and camping stoves.
