NEET Chemistry Molecular Orbital Theory MCQ Question
Type: MCQ-conceptual-Hard-Class 11
Which of the following statements about covalent bonds and molecular structure is correct?
A
Covalent bonds can be both polar and nonpolar depending on the electronegativity differences between atoms.
B
All covalent bonds are formed by head-on overlap of atomic orbitals.
C
The bond angle in NH3 is exactly 90° due to hybridization.
D
A polar bond cannot have a dipole moment if the molecule is symmetrical.
Correct Answer
Option A
Detailed Explanation
Covalent bonds can indeed be polar or nonpolar based on the electronegativity of the atoms involved, as stated in the discussion of polar and nonpolar covalent bonds. Other options present misconceptions about bonding and molecular geometry.
