Order the following bonds from the least polar to the most polar.

N-O, Ca-O, C-O, O-O, Ni-O

O-O < N-O < C-O < Ca-O < Ni-O

O-O < C-O < N-O < Ni-O < Ca-O

Ca-O < Ni-O < C-O < N-O < O-O

O-O < N-O < C-O < Ni-O < Ca-O

Ni-O < Ca-O < C-O < N-O < O-O

S-Cl < P-Cl < Si-Cl < Mg-Cl

To find which bond is the most polar, you need to look at the electronegativity difference between the atoms in the bond. Electronegativity (EN) values in elements increase to the top right corner of the Periodic Table. Mg is the least EN of the other atoms forming bonds with Cl, but it's also the element who is the farthest away from Cl, so they would have greatly differing EN values and be a strong polar bond. S is closest to Cl, so they would have the weakest bond polarity.

No, it is non-polar.


What are the different types of chemical bonds?

Ionic bonds, Covalent bonds, Hydrogen bonds, Polar Covalent bonds, Non-Polar Covalent bonds, and Metallic bonds.


How does a molecule that has polar bonds be nonpolar?

A molecule with polar bonds can be overall non-polar if the bond dipoles cancel each other out. For example the following all have polar bonds but the bond dipoles cancel each other out (vector addition) to make the molecule non-polar. Linear - CO2 trigonal planar - BF3 tetrahedral molecules, CF4 trigonal bipyramidal PF5 octahedral SF6
