Analyzing +4 | -1
Arrange the following compounds in decreasing order of their dipole moment.

I. CH3−CH2−NO2\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{NO}_2

II. CH3−CH2−NH2\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{NH}_2

III. CH3−CH2−F\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{F}

IV. CH3−CH2−C≡N\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{C} \equiv \mathrm{N}
View answer and explanation
Correct option: D
I >> IV >> III >> II
Option D is correct. The order of decreasing dipole moment is I > IV > III > II, based on the electronegativity differences and molecular geometry.
