Name: 1. (9 points) Draw the condensed structure and calculate the molar masses (to four significant figures) for each liquid used in this lab. Record your answers in the table 2 below. Water has been completed for you as an example. Table 2: Pre-lab Question #1 Answers Name Condensed Structure Molar Mass (g/mol) Ethyl alcohol Propyl alcohol n-pentane Butyl alcohol n-hexane Methyl alcohol H-OH water 18.02 (Water looks funny here because I wanted to highlight its structure in a way like alcohols) 2. (1 point) Home lab observation (if you have the substances, otherwise watch this video): Place droplets of water and either ethyl alcohol or isopropyl alcohol (rubbing alcohol) on a penny. a. Which substance has higher surface tension: the water or the alcohol? b. Which substance evaporates easier the water or the alcohol? (hint: substances with low surface tension evaporate more easily) Lab week 3: Intermolecular Forces - W21 Last Updated: 1/19/2021 Page 9 of 9Step by Step Solution
