Draw a lewis structure for hccl3. show all unshared pairs and the formal charges

Answers

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.

The given molecule is, HCCl_3

Carbon has '4' valence electrons, hydrogen has '1' valence electron and chlorine has '7' valence electrons.

Therefore, the total number of valence electrons in HCCl_3 = 1(1) + 1(4) + 3(7) = 26

According to electron-dot structure, there are 8 number of bonding electrons and 18 number of non-bonding electrons.

The electron-dot structure of HCCl_3 is shown below.

Now we have to calculate the formal charges on carbon, hydrogen and chlorine.

Formula for formal charge :

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

text{Formal charge on carbon}=4-0-frac{8}{2}=0

text{Formal charge on hydrogen}=1-0-frac{2}{2}=0

text{Formal charge on chlorine}=7-0-frac{2}{2}=0

1.from liquid state to gaseous state is evaporation 3.solid to liquid is melting 5. solid to gaseous state is sublimation 6. gas to solid state is decomposition 7. a change of state is known as the states of matters

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d
