Dipole moment order : CH3Cl CH2Cl2 CHCl3 CCl4 ? Explain your ans.?
Dipole Moment Order: CH3Cl, CH2Cl2, CHCl3, CCl4

Introduction:
The dipole moment is a measure of the polarity of a molecule, indicating the separation of positive and negative charges within the molecule. It is influenced by the electronegativity difference between atoms and the molecular geometry. In this case, we need to determine the dipole moment order for the compounds CH3Cl, CH2Cl2, CHCl3, and CCl4.

Explanation:
To understand the dipole moment order, we need to consider the bond polarities and the molecular geometry of these compounds.

1. CH3Cl:
- The carbon-hydrogen bond in CH3Cl is polar due to the difference in electronegativity between carbon and hydrogen.
- The carbon-chlorine bond is also polar because of the electronegativity difference between carbon and chlorine.
- The molecular geometry of CH3Cl is tetrahedral, with the chlorine atom being the central atom.
- The dipole moments of the individual polar bonds do not cancel each other out due to the asymmetrical molecular geometry.
- Therefore, CH3Cl has a net dipole moment.

2. CH2Cl2:
- CH2Cl2 has two chlorine atoms bonded to the central carbon atom, resulting in an asymmetrical molecular geometry.
- The dipole moments of the carbon-chlorine bonds do not cancel each other out due to the asymmetry.
- Therefore, CH2Cl2 has a net dipole moment.

3. CHCl3:
- CHCl3 has three chlorine atoms bonded to the central carbon atom, resulting in a trigonal pyramidal molecular geometry.
- The dipole moments of the carbon-chlorine bonds do not cancel each other out due to the asymmetry.
- Therefore, CHCl3 has a net dipole moment.

4. CCl4:
- CCl4 has four chlorine atoms bonded to the central carbon atom, resulting in a symmetrical tetrahedral molecular geometry.
- The dipole moments of the carbon-chlorine bonds cancel each other out due to the symmetry.
- Therefore, CCl4 has a net dipole moment of zero.

Dipole Moment Order:
Based on the explanations above, the dipole moment order is as follows:

1. CH3Cl (net dipole moment)
2. CH2Cl2 (net dipole moment)
3. CHCl3 (net dipole moment)
4. CCl4 (no net dipole moment)

Summary:
The dipole moment order for the given compounds is CH3Cl > CH2Cl2 > CHCl3 > CCl4. The dipole moment depends on the polarity of the individual bonds and the overall molecular geometry. Compounds with an asymmetrical molecular geometry tend to have a net dipole moment, while those with a symmetrical molecular geometry have no net dipole moment.

Dipole moment order : CH3Cl CH2Cl2 CHCl3 CCl4 ? Explain your ans.?
CH3Cl>CH2Cl2>CHCl3>CCl4. .1-This is due to in CH3Cl chlorine is EWG and it is in one direction and no other group present for cancelling/decreasing its dipole moment. 2- In CH2Cl2 dipole moment of H-H atoms and Cl-Cl atoms do not cancel each other because angle are not 180° so they are not linear. 3- In CCl4 dipole moment cancel and become zero because angle between trans position of Cl atom is 180°.
