Step 1:
I'll solve this step-by-step, following the LaTeX formatting guidelines precisely:

Step 2:
: Identify the atoms and their valence electrons

- Carbon (C): 4 valence electrons - Hydrogen (H): 1 valence electron - Oxygen (O): 6 valence electrons

Step 3:
: Count total valence electrons

- Total valence electrons: $$8 + 4 + 12 = 24$$ electrons
- 4 Hydrogen atoms: 1 \times 4 = 4 electrons

Step 4:
: Arrange atoms and connect with single bonds

- Central carbon atom connected to:

Step 5:

Methyl group ($$\mathrm{CH}_3$$)

Step 6:

Carboxyl group ($$\mathrm{COOH}$$)

Step 7:
: Distribute remaining electrons as lone pairs

- Place electrons around oxygen atoms first - Ensure each atom follows octet rule

Step 8:
: Draw Lewis structure

- Single bonds between atoms - Lone pairs on oxygen atoms - Double bond between carbon and one oxygen - Single bond between carbon and other oxygen - Hydrogen attached to terminal oxygen

Final Answer

\mathrm{CH}_3\mathrm{COOH} Lewis structure with: - Single bonds between carbon atoms - Double bond between carbon and one oxygen - Single bond between carbon and other oxygen - Hydrogen attached to terminal oxygen - Lone pairs on oxygen atoms to complete octets
