NEET Chemistry Molecular Orbital Theory MCQ Question
Type: MCQ-conceptual-Hard-Class 11
Which of the following statements about covalent bonding and molecular structure is correct?
A
A polar covalent bond is formed when electrons are shared unequally between two atoms with different electronegativities.
B
Lewis structures can accurately predict all molecular properties without limitations.
C
Triple bonds always result in a linear molecular geometry regardless of surrounding atoms.
D
All covalent bonds are nonpolar, as electrons are always shared equally between bonded atoms.
Correct Answer
Option A
Detailed Explanation
A polar covalent bond occurs when the shared electron pair is displaced towards the atom with higher electronegativity, as seen in HF. Options B, C, and D misrepresent the nature of covalent bonding and Lewis structures.
