CHALLENGE 1
Be the first person to make a molecule with a
bent shape using the molecular modeling kits.
CHALLENGE 2
Be the first person to, while using the molecular
modeling kits, make an NH3 molecule and
identify the vsepr shape.
CHALLENGE 3
Draw the Lewis dot structure of a HCN molecule
and identify the vsepr shape
CHALLENGE 3 ANSWER
Linear
CHALLENGE 4
Draw the Lewis dot structure of H2S and display
the polarity of the bonds
CHALLENGE 4 ANSWER
QUESTION 4
•What is defined as a molecule that has a more
positively charged side and a more negatively
charged side?
ANSWER 4
Dipole
CHALLENGE 5
•Draw the Lewis dot structure of a CF3H molecule
and justify whether or not it is polar.
CHALLENGE 5 ANSWER
•The molecule is polar because
the individual polarities of the
bonds do not all cancel out,
causing the molecule as a
whole to exhibit a polarity.
QUESTION 6
•Which intermolecular force (IMF) is present in
all polar molecules?
ANSWER 6
Dipole interactions
QUESTION 7
•Which of the intermolecular forces occurs
between an electronegative atom on one
molecule and a partially positive charged
hydrogen on another molecule?
ANSWER 7
Hydrogen bonding
QUESTION 8
•Which intermolecular force is caused by the
movement of electrons?
ANSWER 8
London dispersion forces
QUESTION 9
•List the intermolecular forces in order of
increasing strength.
ANSWER 9
Weakest: london dispersion forces;
Middle: dipole interactions;
Strongest: hydrogen bonding
QUESTION 10
•Name all of the intermolecular forces
experienced by the molecule HCN.
ANSWER 10
Dispersion forces and dipole interactions
