Question

Which of the given has the highest dipole moment: CO2, HI, H2O, SO2

Answer 1

Answer:

SO2

Explanation:

it has angular bent shape i.e. v-shape and the compound is non-symmetric

Answer 2

Water has the highest dipole moment.

• The dipole moment of a compound measures its polarity.
• Carbon Dioxide is a linear molecule so, its dipole moment is in opposite directions and cancels out each other giving a net dipole moment zero.
• Sulfur dioxide and water both have bent shapes and a higher dipole moment but due to the large size and low electronegativity of Sulfur, it has somehow low dipole moment than water.
• Due to the large size of I HI has a low dipole moment.
