5th ques. Please tell why the other options are incorrect as well.
Dear Student
CHF3 has highest dipole moment as C-F bond is more polar as compared to C-Cl bond.
CHF3 has highest dipole moment as C-F bond is more polar as compared to C-Cl bond.
CHCl3 has more dipole moment.Because CHCl3 is more polar than CH4 and CCl4.
And CCl4 is non polar so dipole moment is zero here.
