Pls can you explain how to get the observation below Physical properties of Hydrocarbons:   Test for water solubility of hydrocarbons:    1. Label three test tubes as alkanes, alkenes and aromatics. 2. Add 4 drops of each in their respective test tube; add equal amounts of distilled water. Gently swirl. Water is polar solvent. Are there any separations of layers between the water layer and organic liquid layer?  If separated, which layer is on top, the organic layer or thewater layer? 3. Record your observations in the data table below. If separation of layers occurs, increase the amounts of water and gently swirl again to            confirm the insolubility property. 4. Disposal:  All contents to be disposed into the waste container marked as organic waste. Wash the test tubes and clean them using brush, soap and water. Keep these inverted in the test tube rack.

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.
