Chemistry Hydrocarbon

Kindly consider the following Image 

Terminal alkynes and Non Terminal Alkynes are both variants of alkynes, but the difference lies in the position of the triple carbon bond. Terminal Alkynes have the triple carbon bond at the end of the chain, such as ethyne and propyne. On the other hand, Non Terminal Alkynes have their triple carbon bond in the middle of the chain. Example: 2-Butyene.

According to this rule, when a hydrogen halide (HX) or water is added to an asymmetrical alkene, the hydrogen atom (H) gets attached to the carbon atom of the double bond which has more hydrogen atoms, and the halide (X) or OH group attaches to the carbon atom which has fewer hydrogen atoms.

The most common method used for the identification of alkenes is the bromine water test. We simply have to add a few drops of bromine water to the compound which is to be identified. If the compound actually is an alkene, the reddish brown colour will get decolorized (? bond reacts with bromine and breaks the double bond).

Here are the important applications of alkanes in our everyday lives:

• Fuel in Vehicles
• Heating and Cooking
• Lubrication
• Power Generation
• Wax and Solvents

This happens due to the fact that they possess strong C-C and H-H bonds which are non-polar sigma bonds and cannot be broken easily. Also, they lack polar functional groups and are saturated hydrocarbons. These properties combined make them less reactive overall.
