CHEM 219 MODULE 5 PROFESSIONAL
EXAM REVIEW WITH TESTED QUESTIONS
AND EXPERT SOLUTIONS

◉ Phenols
Answer: Hydroxyl group directly attached to a benzene ring


◉ Methyl Alcohol
Answer: Only H atoms attached to the carbon bearing the-OH
group


◉ Primary Alcohol
Answer: one alkyl group attached to the carbon atom bonded to
the -OH group


◉ Secondary Alcohol
Answer: Two alkyl groups attached to the carbon atom bonded to
the -OH group


◉ Tertiary Alcohol
Answer: Three alkyl groups attached to the carbon atom bonded
to the -OH group


◉ Boiling Point of Alcohols

, Answer: High due to Hydrogen bonding between the positively
charged H and negatively charged O


◉ Water solubility of alcohols
Answer: As the carbon chain length increases alcohol becomes
correspondingly less soluble in water.


◉ Alcohols Acidity/Basicity
Answer: Can act as a weak base (accepting H+ using a lone pair on
the O atom) or weak acid (donating the O-H proton as H+)


◉ Amphoteric
Answer: a substance that can act as both an acid and a base


◉ Alkoxide Ion
Answer: conjugate base of an alcohol, very strong base


◉ Alkyloxonium Ion
Answer: The conjugate acid of the alcohol is often called a
protonated alcohol,


◉ Dehydration
Answer: Loss of water. An alcohol molecule will lose H2O to form
an ALKENE. Type of elimination reaction — lose the -OH from one
C and H atom from the adjacent C.
