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.

None of these

Explanation:

:-

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 :

Formal charge for oxygen:

From the structure,

Number of bond pairs = 4 (Double bond)

Number of lone pairs = 4

Hence, the correct option is:-   None of these

here we have to get the change of moles on decrease the volume of the reaction in gas phase.

the   per the given options it will decrease by (d) 11-50%

we know, on decreasing the volume of the gas phase reaction the reaction moves to the product side.

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:                   1 - α               α               α           = 1 + α

(concentration = moles/volume, as volume is 1 l)

(where α is the degree of dissociation)

now the dissociation constant in terms of concentration is :

=  

or,

or,   = (at v = 1l)

the reaction:                     so₂cl₂ (g) = so₂ (g) + cl₂ (g)         total

the moles at equilibrium:   1 - α                 α               α           = 1+α

concentrations:               (1 - α)/0.5           α/0.5         α/0.5       = (1 + α)/0.5

thus, the dissociation constant in terms of concentration is :

or,  

=  

so, the change of 1 : 1/0.5

or, 1: 2

thus it will decrease by 50%.

or, as per the given options it will decrease by 11-50%

b is the correct
