Acetone and Ethanol have similar molar masses but significantly
different delta T values. Explain this based on their
intermolecular forces. The delta T values calculated were -13 for
Ethanol and -22 for Acetone.
Consider the following liquids with similar molar masses.
Predict which has the weakest intermolecular attraction based only
on boiling point data.
butane (Bp @ 760 mm Hg = -0.5 °C)
ethyl chloride (Bp @ 760 mm Hg = 12 °C)
propyl alcohol (Bp @ 760 mm Hg = 97 °C)
acetic acid (Bp @ 760 mm Hg = 118 °C)
ethyl methyl ether (Bp @ 760 mm Hg = 11 °C)
Suppose two seemingly similar goods or services with
significantly different prices. Discuss a minimum of three
different possible explanations of why those price differences
might exist. Be specific about your assumptions. Be clear in why
those goods or services have different prices and whether or not
those price differences might disappear over time. Give examples of
two goods that might fit each of your explanations. What
generalizations about how prices relate to one another can you
make? Focus on the...

1. How is an Analysis of Variance (ANOVA) similar to and
different from a t-test for two samples?
2. Why is it impossible to calculate a negative F value when
using an Analysis of Variance to test a hypothesis?
Please answer both questions
a)How does molar mass (or size) affect the magnitude of alcohol
∆t values?
b)How does hydrogen bonding affect ∆t values?
c)How does branching affect ∆t values among alcohol
isomers?
d)How does molar mass (or size) affect the magnitude of alkane
∆t values?
e)How do ∆t values for the evaporation of 1-propanol
and isopropanol compare?
f)Which type of intermolecular attractions is changing in
strength as the alcohols grow larger?
delta t values that were measured: methanol -7.7, ethanol -9.1,
isopropanol -9.4,...
