Ethers possess a dipole moment even if the alkyl groups in the molecule are identical. Explain.

Text Solution

Verified by Experts

Ethers have angular structure similar to water in which oxygen involves `sp^3` hybridisation. Oxygen is surrounded by two O-R bonds and two lone pairs. Due to angular structure ethers have dipole moment even if the two alkyl groups are identical because two C-O bond moments do not cancel each other. For example Dimethyl ether has dipole moment of 1.3 D.

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 ?
