Write a Lewis structure for `"CC"l_(2)F_(2)` one of the compounds indicated in the depletion of stratoshpheric ozone .

Explanation

Step:1 Place the atmos relative to each other. In `C Cl_(2) F _(2)` carbon has the lowest group number and EN, so it is the central atom. The other atoms surround it but their specific positions are not important
`{:(" "Cl), (""F " "C " "F),(" "Cl):}`
Step:2 Determine the total number of valence electrons :
`[ 1 xx C (4e ^(-))] + [ 2xx F(7e^(-)) ]+ [ 2xx Cl (7e ^(-)) ] = 32` valence `e ^(-)`
Step :3 Draw single bonds to the central atom and subtract `2e ^(-)` for each bond : single bond use `Se ^(-)` so `32e ^(-)- 8e ^(-)` leves `24 e ^(-)` remaining
Step :4 Distrubute the remaining electrons in pairs, beginning with the surround d-atoms so that each has an octet.
