Correct dipole moment order is:
`underset((p))(CH_(2)=CH-Cl)`,`underset((q))( CH_(3)-CH_(2)-Cl)`, `underset((r))( CH_(2)=CH-CN)`

CH_(2)=underset(Cl)underset(|)(C)-CH=CH_(2)

Arrange the following halides in the decreasing order of S_(N^(1)) reactivity : underset((I))(CH_(3)CH_(2)CH_(2)Cl), underset((II)) (CH_(2)=CHCH(Cl)CH_(3)), underset((III))(CH_(3)CH_(2)CH(Cl)CH_(3))

CH_(3)-underset(Cl)underset(|)(CH)-COOH

CH_(3)-underset(OH)underset(|)(CH)-CH_(2)Cl

Arrange following compounds in decreasing order of their dipole moment. underset("I")(CH_(3)-CH_(2)-NO_(2))" "underset("II")(CH_(3)-CH_(2)-NH_(2))" "underset("III")(CH_(3)-CH_(2)-F)" underset("IV")(CH_(3)-CH_(2)-C-=N)

CH_(3)=underset(Cl)underset(|)(C)=CH-CH_(2)-CH_(2)OH
