Write a three-dimensional formula for each of the following molecules using the wedge-dashed wedge-line formalism. If the molecule has a net dipole moment, indicate its direction with an arrow, →. If the molecule has no net dipole moment, you should so state.
(You may ignore the small polarity of C-H bonds in working this and similar problems.)

(b) CH2F2
(c) CHF3
(d) CF4

(g) BeF2
(h) CH3OCH3
(i) CH3OH
(j) CH2O
