Question

Which of these bonds is the least polar?

Which of these bonds is the least polar? O Mg-N O Si-F O All are equally polar. O P-I O Hg-I

Answer 1

Least polar bond is P-I

Polarity depends on the elements electronegativity. If two elements electronegativity difference is more, then that is more Polaro Element : Mg Ini si IFI Plug|I Electronegativity; 1-2 3-0 18 20 22 1975 Mg-N 5 difference 3.0-1-2 = 1.8 si - F =) difference 4.0-1.8 - 2.2 → difference 2.5-2.1 = 0.4 IP-I Hg I difference 2.5-1.9 = 0.6 Least electronegativity difference. : Least Polar is pa
