If you know the polarity of molecules, you can predict whether or not they will mix together to form chemical solutions. On the other hand, octane and water do NOT have similar polarities, so octane will not dissolve in water. This difference arises from the fluorine atoms acting as electron withdrawing groups, attracting essentially all of the lone pair electrons on the nitrogen atom. At the presence … Chemical bond polarity is the concept that explains the property of sharing an electron between two elements. Synthesis and reactivity. So, Is NF3 Polar or Nonpolar? Use periodic trends in bond lengths and the electronegativity table to answer the following questions: there is covalent bonding nitrogen is more electronegative… The covalent bond formed by two atoms is said to be polar if the atoms differ in their electronegativity.eval(ez_write_tag([[728,90],'techiescientist_com-medrectangle-4','ezslot_4',104,'0','0'])); This is because more electronegative atom attracts the bonded electron pair slightly more towards its side and gains partial negative charge whereas other atom gains partial positive charge. Fluorine being more electronegative pulls the bonded electron pairs slightly more towards its side and gains a partial negative charge due to which polarity rises in the molecule. Polar molecules interact with other molecules of similar polarity to form solutions. Answer =  CLO3-  (Chlorate)  is  Polar What is polar and non-polar? Question =  Is CF2Cl2 polar or  nonpolar ?
