We took notes on intermolecular forces (copy of NOTES at bottom of this post) and used our knowledge of inter- and intramolcular forces to answer lab questions (given below). Then, we began a final exam station review.
HW:
1. study for a quiz next class on inter/intramolecular forces
2. finish your lab by answering the lab questions below:
LAB QUESTIONS
1.Not all attractions are created equal. Explain the key factor that affects the strength of dipole-dipole interactions.
2.Which are stronger, intermolecular forces or intramolecular forces? Cite evidence from your lab data.
3.In determining the strength of the intermolecular forces, it is important to consider the net forces present (all the types of forces present and their relative strengths).
a.State the types of intermolecular forces present in water and in paraffin wax.
b.Explain why water, despite having hydrogen bonding, is a liquid at room temperature whereas wax is a solid.
4. Consider the halogens at room temperature. Explain why fluorine (F2) and chlorine (Cl2) are gases whereas bromine (Br2) is a liquid and iodine (I2) is a solid. (Start by listing the types of IMFs for each substance.)
