Question
Arrange the following compounds in increasing order of dipole moment.
\[\ce{CH3CH2CH3, CH3CH2NH2, CH3CH2OH}\]
Advertisements
Solution
\[\ce{CH3CH2CH3 < CH3CH2NH2 < CH3CH2OH}\]
Since O is more electronegative than N, therefore, dipole moment of ethyl alcohol is higher than that of ethylamine. Propane however, has the least dipole moment since it is almost a non-polar molecule.
