Answer :
Explanations:
A lewis structure is a simplified form of representing valence electrons of a compound.
For the compound CHF3, we will follow the steps below to write its lewis diagram
Step 1: Add4 valence electrons around the carbon atom as shown:
Step 2: Add dots to the Fluorine atom and hydrogen atom
Step 3: Combine the two steps above to have:
This gives the required lewis diagram for CHF3
