How do u make this in a lewis dot structure?
C2H3Cl3
thnx :)
To create a Lewis dot structure for C2H3Cl3 (trichloroethylene), let's break down the molecule and assign the correct number of valence electrons to each atom:
- Carbon (C) has 4 valence electrons.
- Hydrogen (H) has 1 valence electron.
- Chlorine (Cl) has 7 valence electrons.
To get the total number of valence electrons for C2H3Cl3, we add up the valence electrons from each atom:
(2 carbon atoms x 4 valence electrons) + (3 hydrogen atoms x 1 valence electron) + (3 chlorine atoms x 7 valence electrons) = 2(4) + 3(1) + 3(7) = 8 + 3 + 21 = 32
With 32 total valence electrons, we can start creating the Lewis dot structure by following these steps:
1. Determine the central atom:
In this case, carbon (C) is the central atom since it is usually the least electronegative (except when hydrogen is present).
2. Connect the atoms:
Connect the carbon atom to the hydrogen atoms and chlorine atoms using single bonds (one pair of electrons). Each hydrogen atom should be bonded to a carbon atom, and each carbon atom should be bonded to a chlorine atom.
3. Add lone pairs (non-bonding electrons):
Fill the remaining valence electrons (after bonding) around each atom starting with the atoms that are not the central atom. Place lone pairs of electrons around each atom until they have a full octet (except for hydrogen, which can only hold 2 electrons).
Here is the Lewis dot structure for C2H3Cl3:

Each hydrogen atom is bonded to the central carbon atom, and each chlorine atom is also bonded to the central carbon atom. The remaining valence electrons are placed as lone pairs around each atom to complete their octets.
To create a Lewis dot structure for C2H3Cl3, follow these steps:
Step 1: Determine the total number of valence electrons.
Carbon (C) has 4 valence electrons, Hydrogen (H) has 1 valence electron, and Chlorine (Cl) has 7 valence electrons. Since there are two carbon atoms, you will need to multiply the valence electrons of carbon by 2.
2(C) + 3(H) + 3(Cl) = 2(4) + 3(1) + 3(7) = 8 + 3 + 21 = 32 valence electrons.
Step 2: Arrange the atoms.
Place the carbon atoms (C) in the middle, connecting them with a double bond and a single bond. Hydrogen (H) atoms will be attached to the carbon atoms, and chlorine (Cl) atoms can be placed on the outside.

Step 3: Distribute the remaining valence electrons.
Start by placing the remaining valence electrons around the atoms to fulfill their octet. Hydrogen atoms only need 2 valence electrons, so place one electron on each hydrogen atom.

Step 4: Fill the octet of carbon and chlorine atoms.
Since carbon and chlorine atoms require 8 electrons each to complete their octets, fill in the remaining valence electrons around them. In this case, each carbon atom has 6 valence electrons, and each chlorine atom has 7 valence electrons.

Step 5: Check the octet of each atom.
Make sure that each atom (except hydrogen) has 8 electrons around it. In this structure, carbon and chlorine atoms satisfy the octet rule. Hydrogen atoms have a duet, which is also acceptable.
Thus, the Lewis dot structure for C2H3Cl3 is complete.
