WitrynaQuestion: Use the electronegativity values from Table 1.2 (below), to determine if the following bonds are likely to be non-polar covalent, polar covalent, or ionic. Match each bond to its appropriate classification. Group 1 Group 2 Group 13 Group 14 Group 15 Group 16 Group 17 H 2.20 Li 0.98 Be 1.57 B 2.04 с 2.55 N 3.04 o 3.44 F 3.98 S Na … Witryna18 godz. temu · To determine if a bond is polar or not we must find out the difference between the electronegativity values of the two atoms sharing a bond. The difference between the electronegativity values of B and F is equal to 1.94 (3.98 – 2.04 = 1.94) which is greater than 0.5. Thus, each B-F bond in BF3 (Boron Trifluoride) molecule is …
