Alkyl halides though polar, are immiscible with water, why ?

Alkyl halides are insoluble in water because they donot form ............. with water.

Why are ethers polar in nature ?

In general, alkyl halides are more reactive than aryl halides.

Write names of some liquids which are immiscible water.

Alkyl halides are regarded as synthetic tools in the hands of a chemist. Justify.

Choose the correct alternative : Reaction of alkyl halide with potassium sulphite gives thioethers / thioalcohols.

Read the given passage and answers following questions : The cleansing action of soap is due to emulsification and micelle formation. Soaps are basically sodium and potassium salts of long chain fatty acids, R-COO- Na^(+) . The end of the molecule to which the sodium is attached is polar in nature, while the alkyl-end is non-polar. Thus, a soap molecule contains a hydrophilic (polar) and a hydrophobic (nonpolar) part. When soap is added to water containing dirt, the soap molecules surround the dirt particles in such a manner that their hydrophobic parts get attached to the dirt molecule and the hydrophilic parts point away from the dirt molecule. This is known as micelle formation. Thus, we can say that the polar group dissolves in water while the non-polar group dissolves in the dirt particle. Now, as these micelles are negatively charged, they do not coalesce and a stable emulsion is formed. What is polar and non-polar groups ?
