What's the lewis dot structure for CH2Cl2 ??
To find the Lewis dot structure for CH2Cl2 (dichloromethane), we need to determine the number of valence electrons for each element in the molecule.
Carbon (C) is in Group 4, so it has 4 valence electrons.
Hydrogen (H) is in Group 1, so it has 1 valence electron.
Chlorine (Cl) is in Group 7, so it has 7 valence electrons.
Next, we add up the total number of valence electrons:
C (1 atom) = 4 valence electrons x 1 atom = 4
H (2 atoms) = 1 valence electron x 2 atoms = 2
Cl (2 atoms) = 7 valence electrons x 2 atoms = 14
Total valence electrons: 4 + 2 + 14 = 20
Once we have the total number of valence electrons, we can start constructing the Lewis dot structure.
1. Place the carbon atom (C) in the center, as it is the least electronegative atom in the molecule.

2. Attach the hydrogens (H) and chlorines (Cl) around the carbon atom, using a single bond (represented by a line) for each bond. Hydrogen should be on the outside since it can only form 1 bond, while chlorine can form multiple bonds.

3. Distribute the remaining electrons around each atom to satisfy the octet rule (except hydrogen, which only needs 2 electrons). Start by placing a lone pair of electrons around each chlorine atom.

4. Distribute the remaining electrons around the carbon atom (in the form of lone pairs) until it has a complete octet (8 electrons). For CH2Cl2, two electrons will remain, which are placed as a lone pair on the carbon atom.

5. Finally, check that each atom has a full outer shell (except hydrogen with 2 electrons). In this case, carbon and chlorine have 8 electrons, and hydrogen has 2 electrons.

So, the Lewis dot structure for CH2Cl2 is:

It is important to note that the Lewis dot structure represents the valence electrons of the atoms and the bonding pairs between them, but it does not provide information about the 3D molecular structure or the bond angles.
I couldn't find a CH2Cl2 dot structure on the net; however I found CCl4. You can emulate that and exchange two of the Cl atoms with H atoms. The two H atoms will have a H:C:H with Cl on top and bottom.
