level questions: Alcohols (HARD)
Question
Answer
Organic compounds containing the -OH (hydroxyl) functional group.
Alcohols
What functional group characterizes alcohols?
Alcohols contain the -OH (hydroxyl) functional group.
The -OH group, consisting of an oxygen atom bonded to a hydrogen atom.
Hydroxyl Functional Group
What does the hydroxyl functional group look like, and is it found in alcohols?
The hydroxyl functional group is represented as -OH and yes, it is found in alcohols.
The different ways alcohols can be symbolically represented.
Representation of Alcohols
How can alcohols be represented, and what are the two common ways of doing so?
Alcohols can be represented using structural formulas or molecular formulas. The two common ways are: Structural Formula, Molecular Formula
The simplest alcohol, with the molecular formula CH₃OH.

What is the molecular formula for methanol, and what type of alcohol is it?
Methanol has the molecular formula CH₃OH and is the simplest alcohol.
A type of alcohol with the molecular formula C₂H₅OH, commonly found in alcoholic beverages.
Ethanol
What is the molecular formula for ethanol, and where is it commonly found?
Ethanol has the molecular formula C₂H₅OH and is commonly found in alcoholic beverages.
An alcohol with the molecular formula C₃H₇OH.
Propanol
What is the molecular formula for propanol?
The molecular formula for propanol is C₃H₇OH.
An alcohol with the molecular formula C₄H₉OH.
Butanol
What is the molecular formula for butanol?
The molecular formula for butanol is C₄H₉OH.
Hydrocarbons that contain a carbon-carbon double bond.
Alkenes
What type of organic compounds react with water (steam) to form alcohols?
Alkenes react with water (steam) to form alcohols.
A process that leads to the transformation of one set of chemical substances to another.
Chemical Reaction
What type of reaction results in the formation of alcohols from alkenes and water (steam)?
The reaction between alkenes and water (steam) is a chemical reaction that forms alcohols.
Compounds consisting of hydrogen and carbon atoms only.
Hydrocarbons
What structural feature do alkenes have that allows them to react with water to form alcohols?
Alkenes have a carbon-carbon double bond, which makes them reactive and allows them to undergo reactions with water to form alcohols.
