Final exam random facts CHEM, questions and answers, 100% accurate answers incomplete octet Another significant exception to the octet rule involves those elements that tend to form Which pair of atoms forms the most polar bond? C and O N and O N and F C and F The greater the electronegativity difference between the bonding atoms, the more polar the bond. F is the most electronegative of these elements and C is the least electronegative, therefore the bond between them is the most ...
