CH3Cl intermolecular forces has dipole-dipole forces and London dispersion forces.the chemical name of CH3Cl is chloromethane.
Hello, reders today we will discuss about what is the intermolecular forces of ch3cl and polarity
I have made this guide to help you out. So, hold your seat and be with the end of guide.
So, you could get valuable information out of it.

CH3Cl intermolecular forces
The chemical name of this compound is chloromethane. If you see properly the structure of chloromethane, carbon with the three hydrogen (ch3) and chlorine (Cl) are attached to it. and charge between carbon hydrogen, it is form C-H (carbon- hydrogen) bonds. that this bonds is non polar. and it is also form C-Cl (carbon-chlorine) bonds. but this bonds is polar.
You know that, chlorine has more electronegative compare with carbon. due to this, it is make partial positive charge on carbon and partial negative charge on chlorine. due to this charge it interact each other and the direction of bond dipole between carbon and chlorine is upwards. It mean, it generate dipole moment between C-Cl and C-H. this type of intraction is called dipole-dipole intraction.
therefore, you can say that, ch3cl has dipole dipole intraction. and carbon-chlorine bonds are slightly stronger then carbon-hydrogen.
London dispersion forces
London dispersion forces occurs specially in non polar molecules. Consider the neutral atoms. In case of neutral atoms, electrons are equally distributed. You know that electron are constantly revolving around the neuclie. the structure of atoms are distributed as shown in figure.
here, one side of atoms, there is more electrons, then it make partial negative because it contains more electrons and other side of atoms, there is less electron. So, it make partial positive charge because it contain less electrons. therefore, these type of intraction is called dipole-dipole intraction.
It has two types of pole.
1. Positive pole
2. Negative pole
this atoms also become a neutral atoms. So, we can say that it is temporary dipole.
temporary dipole:- Temporary dipole is a dipole when the electronic cloud neutral atoms is destroyed for the time being.
Dipole moment in ch3cl
first you draw the structure of ch3cl
First of all, i will explain about charge for C-Cl bonds and C-H bond.
charge between carbon and chlorine – chlorine has high electronegativity then carbon. So, chlorine has partial negative charge whereas carbon has partial positive charge.
charge between carbon and hydrogen – carbon has highly electronegativity then hydrogen. so, carbon has partial negative charge whereas, hydrogen has partial positive charge.
the direction of bond dipole between chlorine and carbon is upwards. similarly, the direction of bond dipole is same in carbon hydrogen. but some bond dipole is cancel out but overall the bond dipole is greater. therefore, you can say that, the net dipole moment is very good in ch3cl.
Ch3Cl Polar or Non Polar
You know that, dipole dipole interaction occurred in polar molecules. but how you can say that ch3cl is polar molecules or non polar molecules. lets get to now about it is “polar or non polar”.
CH3Cl is polar molecules because carbon are attached with three hydrogen, it is non polar, and london dispersion forces occurs non polar molecules but carbon – chlorine is polar molecules. because chlorine has more electronegative charge then carbon. So, it hold electron on it.
