Chiral stationary phases based on amino acid derivatives, cyclodextrins, chiral silanes, etc are capable to separate enantiomers, because one form is slightly stronger bonded than the
Namun, sebagian besar waktu ketika orang berbicara tentang molekul polar yang mereka maksud adalah molekul kovalen polar dan tidak semua
Figure (PageIndex{1}) Some examples of nonpolar molecules based on molecular geometry (BF 3 and CCl 4 )
If the electronegativity difference between the atoms is 0
The prime difference between polar and nonpolar solvents is, the polar solvent gets dissolved in a polar compound, whereas the non-polar solvent gets dissolved in non-polar compounds
Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms
The Big Six polymers are generally nonpolar molecules and therefore do not dissolve in polar solvents such as water
Polar substances have enough positive and negative electrical charges on the atoms while non-polar substances do not have abundant charges
