Write the lewis structure for each molecule (octet rule not followed). a. bbr3 b. no c. clo2

Answer :  The Lewis-dot structure for the given molecule are shown below.

Explanation :

Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.

In the Lewis-dot structure the valance electrons are shown by 'dot'.

(a) The given molecule is,

As we know that boron has '3' valence electrons and bromine has '7' valence electron.

Therefore, the total number of valence electrons in = 3 + 3(7) = 24

According to Lewis-dot structure, there are 6 number of bonding electrons and 18 number of non-bonding electrons.

(b) The given molecule is,

As we know that nitrogen has '5' valence electrons and oxygen has '6' valence electron.

Therefore, the total number of valence electrons in = 5 + 6 = 11

According to Lewis-dot structure, there are 4 number of bonding electrons and 7 number of non-bonding electrons.

(c) The given molecule is,

As we know that chlorine has '7' valence electrons and oxygen has '6' valence electron.

Therefore, the total number of valence electrons in = 7 + 2(6) = 19

According to Lewis-dot structure, there are 4 number of bonding electrons and 15 number of non-bonding electrons.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.
