The BCI3 is a planar molecule whereas NCI3 is pyramidal, because
  • a)
    B-Cl bond is more polar than N-Cl bond
  • b)
    N-Cl bond is more covalent than B-Cl bond
  • c)
    Nitrogen atom is smaller than boron atoms
  • d)
    BCI3 has no lone pair but NCI3 has a lone pairofelectrons
Correct answer is option 'D'. Can you explain this answer?

No lone pair ofelectrons is available in BCI3
One lone pair of electrons is available on N atom, occupies a corner in the tetrahedral arrangement. Therefore, NCI3 appears pyramidal in shape.
