Question 1:

Which type of reaction is used to combine two or more small molecules to form a larger, more complex molecule?

Explanation: The type of reaction used to combine two or more small molecules to form a larger, more complex molecule is called "Addition reaction."

Question 2:

Which functional group is typically present in aldehydes and ketones?

Explanation: The functional group typically present in aldehydes and ketones is the "Carbonyl group."

Question 3:

Which type of reaction involves the breaking of a bond and the addition of atoms or groups to the reactant?

Explanation: The type of reaction that involves the breaking of a bond and the addition of atoms or groups to the reactant is called "Addition reaction."

Question 4:

Which type of reaction involves the removal of a molecule or a functional group from a reactant?

Explanation: The type of reaction that involves the removal of a molecule or a functional group from a reactant is called "Elimination reaction."

Question 5:

Which type of reaction involves the exchange of functional groups between two molecules?

Explanation: The type of reaction that involves the exchange of functional groups between two molecules is called "Displacement reaction" or "Substitution reaction."
