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.

Successful collisions help in the formation of new products, whereas in unsuccessful collisions the molecules just bounce back without causing any reaction. In such cases, the reaction fails and no new product or bond is formed.

For a collision to happen, the molecules must collide with each other at a high frequency. But the result can still lead to disappointment. This is because even if molecules collide effectively, they also need to be aligned properly in symmetry. Only this can help in the formation of new bonds. Hence, the molecular orientation is considered important in he concept of collision theory.
