question 1 (1 point)
what is the molecular formula of salicylic acid?
c7h6o3
c9h8o4
c4h6o3
hc2h3o2

Explanation:

Step1: Recall the structure of salicylic acid

Salicylic acid has a benzene ring (\(C_6H_5-\)), a hydroxyl group (\(-OH\)) and a carboxyl group (\(-COOH\)).

Step2: Count the atoms

• Carbon (\(C\)): \(6 + 1=7\)
• Hydrogen (\(H\)): \(5+1 + 2=8\) (from benzene ring, hydroxyl group and carboxyl group)
• Oxygen (\(O\)): \(1+2 = 3\)

Answer:

\(C_7H_6O_3\)
