Current Question (ID: 7958)

Question:

$\text{The correct Lewis structure of acetic acid is:}$

Options:

1. $\text{H} = \text{C} - \text{C} - \text{O} - \text{H}$ with lone pairs shown as dots
2. $\text{H} = \text{C} - \text{C} = \text{O} - \text{H}$ with lone pairs shown as dots
3. $\text{H} - \text{C} - \text{C} = \text{O}:$ with lone pairs shown as dots (Correct)
4. $\text{None of the above.}$

Solution:

$\text{HINT: Every atom in a lewis structure has a complete octet.}$\n\n$\text{Explanation:}$\n\n$\text{The Lewis dot structures provide a picture of bonding in molecules and ions in terms of the shared pairs of electrons and the octet rule.}$\n\n$\text{1. The first structure is wrong because one of the carbon atom form 5 bonds which are not possible. Carbon can maximum forms four bonds.}$\n\n$\text{2. The second structure is also wrong because one of the oxygen atoms has 10 electrons in its valence shell and it is not possible.}$\n\n$\text{3. The third structure is the correct lewis structure of acetic acid because every atom has a complete octet.}$\n\n$\text{Hence, the third answer is the correct answer.}$
