CHEMICAL BONDING17(b)Fluorine is more electronegative than chlorine, and so its bond to hydrogen is more polar, asthe measured dipole moments indicate.(c)Boron trifuoride is planar. Its individual B@F bond dipoles cancel. It has no dipole moment.(d)A carbon–chlorine bond is strongly polar; carbon–hydrogen and carbon–carbon bonds areonly weakly polar.(e)A carbon–fuorine bond in CCl3F opposes the polarizing effect of the chlorines. Thecarbon–hydrogen bond in CHCl3reinforces it. CHCl3therefore has a larger dipole moment. (f)Oxygen is more electronegative than nitrogen; its bonds to carbon and hydrogen are morepolar than the corresponding bonds formed by nitrogen.(g)The Lewis structure for CH3NO
