Question

Write the correct Lewis dot structure for O2. Which statement correctly describes the structure of the whole molecule? A. There is a single bond, a double bond, and six lone pairs. B. There is a single bond and four lone pairs. C. There is a single bond and six lone pairs. D. There is a double bond and six lone pairs.

Answer 1

Answer:

None of these

Explanation:

$O_2$:-

Valence electrons of oxygen = 6

The total number of the valence electrons  = 2(6) = 12

The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So, The Lewis structure is shown in image below.

Formula for formal charge :

$\text{Formal charge}=\text{Valence electrons}-\text{Non-bonding electrons}-\frac{\text{Bonding electrons}}{2}$

Formal charge for oxygen:

$\text{Formal charge}=6-4-\frac{4}{2}=0$

From the structure,

Number of bond pairs = 4 (Double bond)

Number of lone pairs = 4

Hence, the correct option is:-   None of these
