Which molecular formula corresponds to acetic acid (ethanoic acid)?
A
B
C
D
Verified step by step guidance1
Step 1: Understand the molecular formula of acetic acid (ethanoic acid). Acetic acid is a carboxylic acid with the formula consisting of carbon (C), hydrogen (H), and oxygen (O) atoms.
Step 2: Recall that acetic acid has 2 carbon atoms, 4 hydrogen atoms, and 2 oxygen atoms. This corresponds to the molecular formula \(C_2H_4O_2\).
Step 3: Compare the given options with the known formula \(C_2H_4O_2\). The correct molecular formula must have exactly 2 carbons, 4 hydrogens, and 2 oxygens.
Step 4: Eliminate options that do not match the count of atoms in acetic acid. For example, formulas with fewer or more atoms than \(C_2H_4O_2\) are incorrect.
Step 5: Confirm that the molecular formula \(C_2H_4O_2\) corresponds to acetic acid, as it matches the known composition of this compound.
