Hydroxyl, OH
What is the suffix that all alcohol names end in?
ol
What is the general formula for alcohols?
CnH2n+2O
Describe the trend in melting and boiling point of alcohols as the number of carbon atoms increases.
As the number of carbon atoms increases the melting and boiling point increases.
What pH does an alcohol solution have?
7
Are all alcohols soluble in water? What happens to the solubility as the carbon chain increases?
No. The smaller alcohols are soluble in water. The longer the carbon chain length the less soluble they become in water.

What is the suffix that all carboxylic acids end in?
anoic acid
Describe the trend in melting and boiling point of carboxylic acids as the number of carbon atoms increases.
As the number of carbon atoms increases the melting and boiling point increases.
Are carboxylic acids strong or weak acids?
