How does molecular shape affect polarity? A. If the molecule contains nonpolar bonds, a bent shape will make it
polar.
B. If the molecule contains atoms of similar size, polarity will cancel
out.
C. If the molecule contains more than two bonds, shape will not
affect polarity.
D. If the molecule is symmetrical, the effects of polarity will cancel
out.

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
