Question:
Arrange the following compounds in increasing order of dipole moment.
CH3CH2CH3, CH3CH2NH2, CH3CH2OH
Solution:
CH3CH2CH3 < CH3CH2NH2 < CH3CH2OH
The dipole moment of CH3CH2OH is greater than that of CH3CH2NH2. CH3CH2CH3 has the least dipole moment among the three given compounds because it is almost a non-polar molecule.
