What is the melting and boiling points of alkanes like? - ANSWER--as chain length 
increases so does the strength of the intermolecular forces as there is greater 
surface area for contact between molecules and hence stronger london forces 
and therefore the melting/boiling points are highr for longer chain. 
What is a structura/chain isomer? - ANSWER--Same molecular formula but a 
different structural formula

Title: Bonding and Properties 
Purpose: Study the infrared spectra and physical properties of molecules to determine what 
kinds of intra-molecular bonds are present within the molecules and what kinds of intermolecular bonds are present between the molecules. 
Procedure: 
1. Add potassium chloride (ionic) to water in a test tube. Shake tube so potassium chloride 
dissolves. 
2. Add pentate to test tube of water. Shake to see if it dissolves in the water. 
3. Add normal propyl chloride to test t...
