Question

Which of the following statements are true about the theoretical model of hybridization in covalent compounds? Hydrogen atoms never hybridize their orbitals. O Atoms form hybrid orbitals using of their highest energy atomic orbitals first. Every atom in a covalent molecule must have the same hybridization. Atoms use as many atomic orbitals as they need hybrid orbitals. O Atoms blend some or all of their valence atomic orbitals to generate new hybrid orbitals with which to form bonding electronic domains.

Explanation / Answer

The true statements are:

*Hydrogen atoms never hybridise their orbitals. (Hydrogen has only s orbital, no other orbital in hydrogen to hybridise with)

*Atoms use as many atomic orbitals as they need hybrid orbitals.( No of hybrid orbitals formed equals no of atomic orbitals used, so only as many atomic orbitals will be used as orbitals required)

* Atoms blend some or all of their valance atomic orbitals to generate new hybrid orbitals with which to form bonding electronic domains.( Atom can use some or all of its valance orbital depending upon no of bonds to be made)
