VSEPR/Polarity/IMF Review Game By: Mr. Gates Dubuque Senior High School

Category 1 Properties of bonds

Question 1 Which bond is the longest? Single covalent Double covalent Triple covalent

Answer 1 Single covalent bonds

Question 2 Which bond is the strongest? Single covalent Double covalent Triple covalent

Answer 2 Triple covalent bonds

Question 3 Which bond has the largest bond dissociation energy? Single covalent Double covalent Triple covalent

Answer 3 Triple covalent bond

Category 2 VSEPR shapes

Challenge 1 Be the first person to draw a molecule with a bent shape.

Challenge 1 answer

Challenge 2 Be the first person to draw the Lewis dot structure for an NH3 molecule and identify the vsepr shape.

Challenge 2 answer Trigonal Pyramidal

Challenge 3 Draw the Lewis dot structure of a HCN molecule and identify the vsepr shape

Challenge 3 Answer Linear

Category 3 Polarity

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.

Intermolecular Forces Category 4 Intermolecular Forces

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?

London dispersion forces 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.

Dispersion forces and dipole interactions Answer 10 Dispersion forces and dipole interactions
