# Why does $CH_3Cl$CH3Cl have morea larger dipole moment than $CHCl_3$CHCl3?

Why does $$CH_3Cl$$$$\ce{CH3Cl}$$, methyl chloride, have morea larger dipole moment than $$CHCl_3$$$$\ce{CHCl3}$$, chloroform?

Let us consider $$C-Cl$$$$\ce{C-Cl}$$ bond moment to be $$x$$ and that of $$C-H$$$$\ce{C-H}$$ bond to be $$y$$.

In $$CCl_4$$$$\ce{CCl4}$$, the dipole moment of any three C-Cl$$\ce{C-Cl}$$ atoms is balanced by the dipole moment of the fourth $$C-Cl$$$$\ce{C-Cl}$$ bond dipole moment. This means the resultant of dipole moment of three $$3\ C-Cl$$$$\ce{C-Cl}$$ bonds in tetrahedral structure is equal to $$x$$, which is equal and opposite to the dipole moment $$x$$ of the fourth $$C-Cl$$$$\ce{C-Cl}$$ bond.
Now

Now, when we replace one of the chlorines with a hydrogen, the net dipole moment equals $$x+y$$, (as they are in the same directions). Similarly if we carry out the same procedure for $$CH_3Cl$$$$\ce{CH3Cl}$$ it can be proved that its dipole moment is also $$x+y$$.
