June 2018 NY Regents Chemistry Exam
41 An atom of which element reacts with an atom of hydrogen to form a bond with the greatest degree of polarity?
(2) fluorine (3) nitrogen
Solution: Fluorine is the most electronegative element as can be seen in Table S on the Reference Table. It will result in the most polar bond when bonded to a hydrogen. The most polar bond is the one with the highest electronegativity difference between the two elements.
