Size of molecule depends upon________________?
Correct answer: C. Both A and B
- A. Atomicity
- B. Shape of molecule
- C. Both A and B
- D. Difficult to predict
Explanation
Molecular size is affected by the number of atoms present, called atomicity, and by how those atoms are arranged in space. Therefore both the atomicity and the molecular shape influence the overall dimensions of a molecule. The likely mistake is choosing a by considering only the number of atoms and ignoring that an extended or branched shape can change molecular size.

About Shapes of Orbitals
Atomic orbitals are three-dimensional regions where an electron is most likely to be found, not fixed circular paths. The content covers the spherical s orbitals, dumbbell-shaped p orbitals, clover-shaped d orbitals, the orientations of orbitals, and how quantum numbers determine their shapes and energy levels.
