most polar?
A) C-Cl
B) C-I
C) C-H
D) C-Br. Answer: A) C-Cl
◉ 14) Look at packet for table.
Based on the information given, △Hᵣₓₙ is closest to which of the
following?
A) -165 kJ/molᵣₓₙ
, B) -77 kJ/molᵣₓₙ
C) +77 kJ/molᵣₓₙ

◉ 17) Based on the Lewis diagrams, which of the products is more
soluble in ethanol (C₂H₅OH)?
A) Methane, because it has more hydrogen atoms than water does, sit it
can form more hydrogen bonds with ethanol.
B) Methane, because it is a larger molecule than water, so its electron
cloud is more polarizable.
C) Water, because water has a greater molar mass than methane does.
D) Water, because water molecules can form hydrogen bonds with
ethanol molecules, but methane molecules cannot.. Answer: D) Water,
because water molecules can form hydrogen bonds with ethanol
molecules, but methane molecules cannot.
