Chapter 12, Problem 4STP

Interpretation Introduction

Interpretation:

The correct option is to be selected regarding electronic distribution in the given molecule.

Concept introduction:

Covalent bond is formed by sharing of electrons between the atoms forming the bonds

The bond formed is polar when there is electronegativity difference between the atoms forming the bond due to which atoms gets polarity.

More electronegative atom acquires partially negative charge and less electronegative atom acquires partial positive charge.

Answer to Problem 4STP

C

Explanation of Solution

Oxygen is more electronegative than carbon. Therefore, the bond between $C-O$ is polar covalent bond and electrons are more concentrated towards oxygen than carbon.

Conclusion

Option A is incorrect because atoms forming bond are of different electronegativity.

Option B is incorrect because electronegativity of carbon is less than oxygen.

Option D is incorrect because electron density of a bond can be predicted according to electronegativity values.
