Answers to Intermolecular
Forces HW
Molecular Shape and Polarity
Because all molecules take on different
molecular shapes, some molecules may contain
polar bonds and ultimately be polar OR nonpolar molecules.
Draw each example with its electron pair and
molecular geometry to determine if the molecule
is overall polar or non-polar.

Definitions
Synthesis – two or more simple
substances combine to form a more
complex one.
Ex. A + B  AB
Decomposition – a complex substance
is broken down into two or more
simple substances.
Ex. AB  A + B
Definitions
Single Replacement – an element or ion
moves out of one compound and into
another or by itself
Ex. AB + C  AC + B
Double Replacement – The exchange of
bonds between two reacting substances.
Ex. AB + CD  AC + BD
Definitions
Combustion – burning reaction
between fuel and oxygen resulting in
the release of CO2 and H2O.
Ex. CH4 + 2O2  CO2 + 2H2O
