Polar Protic and Aprotic Solvents. Page ID. Solvents used in organic chemistry are characterized by their physical characteristics. Among the most important are whether the solvents are polar or non-polar, and whether they are protic or aprotic. Because non-polar solvents tend to be aprotic,the focus is upon polar solvents and their structures.In $\ce{CHCl3}$ the dipole moment of the $\ce{C-Cl}$ bond is towards $\ce{Cl}$. Since it has a tetrahedral geometry and the dipole moment is a vector quantity, the vector sum of all dipole moments would try to cancel out. As they are in the outward direction, they will cancel to some extent.While in $\ce{CH2Cl2}$, the $\ce{C-H}$ bond has the dipole towards $\ce{C}$ and there are only two $\ce ...When 30.7 g Cl2 (MM = 70.90 g/mol) reacts with excess CH4, the reaction results in a 80.4% yield.
