NEET Chemistry Molecular Orbital Theory MCQ Question
Which of the following statements about covalent bonding and molecular structure is correct?
A polar covalent bond is formed when electrons are shared unequally between two atoms with different electronegativities.
Lewis structures can accurately predict all molecular properties without limitations.
Triple bonds always result in a linear molecular geometry regardless of surrounding atoms.
All covalent bonds are nonpolar, as electrons are always shared equally between bonded atoms.
Correct Answer
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.
