NEET Chemistry Covalent Bond Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Nonpolar covalent bond | (i) Head-on overlap of orbitals |
| (b) Polar covalent bond | (ii) Shared electron pair displaced |
| (c) Sigma bond | (iii) Equal sharing of electrons |
| (d) Dipole moment | (iv) Result of unequal sharing |
a-iii, b-iv, c-i, d-ii
a-ii, b-i, c-iii, d-iv
a-i, b-ii, c-iii, d-iv
a-ii, b-iv, c-i, d-iii
Correct Answer
Detailed Explanation
A nonpolar covalent bond involves equal sharing of electrons (a-iii), while a polar covalent bond results from unequal sharing, creating a dipole moment (b-iv). A sigma bond is formed through head-on overlap of orbitals (c-i), and the dipole moment arises from this unequal sharing (d-ii).
