Question

Calculate formal charges on the C and O atoms in two resonance structures for acetic acid, the main component of vinegar.

a) +1 (C), -1 (O)
b) 0 (C), 0 (O)
c) -1 (C), +1 (O)
d) +2 (C), -2 (O)

Answer 1

The formal charges on the C and O atoms in the resonance structures of acetic acid are 0 (C) and 0 (O).

Step-by-step explanation:

The formal charges on the C and O atoms in two resonance structures for acetic acid are as follows:

1. +1 (C), -1 (O)
2. 0 (C), 0 (O)
3. -1 (C), +1 (O)
4. +2 (C), -2 (O)

Based on the information given, the correct answer is option b) 0 (C), 0 (O). In the resonance structures of acetic acid, the carbon atom has a formal charge of 0 and the oxygen atom also has a formal charge of 0.
