- Q5Which of the following is true about hybrid orbitals?They result from the mixing of atomic orbitalsThey are only found in ionic compoundsThey have the same shape as atomic orbitalsThey are formed through the overlap of molecular orbitals30s
- Q6Which statement best describes molecular orbital theory?Electrons are shared unequally between atoms to form polar bonds.Molecules are formed by the overlap of hybrid orbitals from different atoms.Electrons are transferred between atoms to form covalent bonds.A combination of atomic orbitals form molecular orbitals that can hold up to two electrons each.30s
- Q7Which of the following is NOT a characteristic of molecular orbitals?Molecular orbitals can exhibit bonding or antibonding interactions.Molecular orbitals can have different energies.Molecular orbitals can accommodate up to two electrons.Molecular orbitals are formed by the linear combination of atomic orbitals.Molecular orbitals are localized around individual atoms.30s
