Question

Which one of the following is/are regarding solubility of alkanes?

• A. Insoluble in water
• B. Soluble in various organic solvent
• C. Both (a) and (b)
• D. Insoluble in Carbon Tetrachloride

Answer 1

The correct option is C Both (a) and (b)

The solibulity of a molecule depends on whether it is a polar molecule or a non-polar molecule. So, polar molecule are soluble in polar solvents and non-polar molecule are soluble in other non-polar solvents.
Alkanes (non-polar) are insoluble in water (polar).
Alkanes (non-polar) are soluble in various organic solvents (non-polar) for example: Benzene. Ether etc.
Hence option (a) and (b)are correct.
