Students have asked these similar questions
1. The boiling points of liquids are determined
by the intermolecular forces that must be
energetically overcome for that liquid to
convert from a liquid to a gas. Consider the
solvents ethanol and dichloromethane.
A. Draw the interaction between ethanol-
ethanol molecules and dichloromethane-
dichloromethane molecules.
Please explain the chosen letter.
Which is NOT a physical property of alcohols or phenols?
a. Phenols are generally only slightly soluble in water.
b. The solubilities of normal primary alcohols in water decrease with increasing
molecular weight.
c. The hydroxyl group of an alcohol is nonpolar.
d. Due to hydrogen bonding, boiling points of alcohols are much higher than those
of corresponding alkanes.
What letters are the false statements below
A.) Methanol, 2-propanol, and ethylene glycol are all toxic when ingested.
B.) 1,2,3-propanetriol is obtained during the manufacture of soap.
C.) Glycerin strongly attracts and holds water, a property that makes it useful as a skin softener in
cosmetics.
D.) Pyran is a cyclic ether.
E.) Heptanol is a water soluble alcohol.
F.) Ethyl ether has been replaced by halogenated anesthetics, which have fewer side effects.
G.) Ethers can only be straight chain compounds.
H.) Furan is an aromatic compound that contains oxygen in the ring.
I.) Dioxanes are aromatic compounds that contain two oxygen atoms in the ring.
J.) Tertiary alcohols are easily oxidized.
K.) Alcohols form hydrogen bonds; this accounts for their higher boiling points when compared to
similar-sized alkanes.
L.) The oxygen atom in alcohols decreases water solubility of the molecule.
M.) Phenols behave as weak acids in water.
N.) Alcohols can…
