Bonds within a molecule are called intra-molecular bonds. Non-polar (type) compounds are insoluble in water. intra-molecular Correct! Non-polar Correct! Question 2 10 / 10 pts Fill in the blanks: Pentane is insoluble in water because it is a/an nonpolar (type) compound. Ethyl alcohol has a boiling point of 76.4 C and n-propyl chloride has a lower boiling point of 46.3 C because the Hydrogen bonds holding ethyl alcohol together are stronger than the nonpolar bonds which hold n-propyl chl...

1. (3 points) In this experiment, what solvent was placed in the test tube? 2. (4 points) Why was warming data used for estimating the freezing/melting point of the cyclohexane? 3. (3 points) In this experiment, how long was the melting process observed? 1. cyclohexane 2. Solids tend to supercool, which gives false data. So, warming data gives a better approximation of freezing/melting point. 3. 8 minutes
