Question

Which molecule is polar, based on structure?

Answer 1

the answer is A sulfur dioxide ..........................

Answer 2

Answer:  Sulphur Dioxide

Explanation:  Polarity of the molecule is basically based on -

a) Electro negativity of the individual atoms

b) Structure of the molecule as change will dipole moment or asymmetric structure will lead to the polar molecule.

Sulfur Dioxide has bent structure with 2 lone pairs and 2 bond pairs. . Thus the molecule is polar

Carbon disulfide has linear structure. Thus there will be no change in dipole moment in the structure thus in non polar.

Ethylene molecule is the most linear molecule thus cannot be polar.

Carbon Tetra chloride is in shape of Tetrahedron thus it is also non polar as no net change in dipole moment can be seen.
