Hydrocarbon Derivatives: Crash Course Chemistry #43

What is the primary role of functional groups in organic chemistry?

• To make compounds smell like fish

• To determine how a compound behaves and reacts

• To make compounds non-polar

• To remove nail polish

What type of organic compound is formed when an alcohol is dehydrogenated?

• A carboxylic acid

• An aldehyde

• A hydrocarbon

• A hydroxyl

Why are simple hydrocarbons generally non-polar?

• They have a high boiling point

• They contain only carbon and oxygen

• The electronegativity difference between carbon and hydrogen is small

• They are always found in liquid form

Which two functional groups combine to form a carboxylic acid?

• Hydroxyl and Alcohol

• Carbonyl and Aldehyde

• Hydroxyl and Carbonyl

• Alcohol and Aldehyde

What property allows carboxylic acids to act as acids in a solution?

• They have strong carbon bonds.

• They contain oxygen atoms.

• Their hydrogen atoms are weakly held and can dissociate.

• They are used to form proteins.

Which common household item contains acetic acid?

• Fire ant bites

• Vinegar

• Nail polish remover

• Wood alcohol

What functional group is characterized by a non-terminal (internal) carbonyl group?

• Alcohol

• Aldehyde

• Ketone

• Amine

How can you distinguish an ether from an ester based on their molecular structure?

• Ethers have more carbon atoms than esters.

• Esters contain a carbonyl group, while ethers do not.

• Ethers have stronger hydrogen bonds.

• Esters are always water-soluble.
