Question

Choose the molecules in which hybridization occurs in ground state

Answer 1

The Question is incomplete here, so I will explain few molecules in which hybridization occurring in ground state.

NH₃, PCl3, PBr₃

Explanation:

Consider NH₃ molecule, the electronic configuration of central atom N is 1s²2s²2p³ where the 3 electrons in p orbit are in 3 p orbitals without being paired.

• They pair each with one H atom in without exciting it, since in ground state itself the p orbitals are unpaired and hybridize in ground state.
• Therefore they pair with 3 H atoms forming molecule NH₃.

Similarly, in the molecules PCl₃ and PBr₃, the electronic configuration of central atom P is 1s²2s²2p⁶3s²3p³ and the outer p-orbit has 3 unpaired electrons in three p-orbitals.

• They share electron with one Cl or Br atom forming PCl₃ 0r PBr₃ respectively.
• therefore, Here also the molecule gets hybridized in ground state.
