Chapter 20: Problem 4

The condition to be satisfied for the atomic orbitals to form molecule orbitals is (a) they must possess comparable energies (b) they must overlap to a considerable extent (c) they must be symmetrical with respect to the molecular axis (d) all the above

Short Answer

Expert verified
The correct answer is (d) All the above.

Step by step solution

01

Analyze the Conditions

Analyze the options provided in the question one by one. Option (a) talks about comparable energies which is crucial for atomic orbitals to form molecular orbitals. Option (b) mentions substantial overlap which is another necessary condition for atomic orbitals to form molecular orbitals. Option (c) talks about symmetry with respect to the molecular axis which is again a fundamental requirement for atomic orbitals to form molecular orbitals.
02

Identify the Correct Answer

As each of these options is a condition that needs to be fulfilled for atomic orbitals to form molecular orbitals, the correct answer is that all these options (a, b, c) are necessary conditions. Hence, option (d) is the correct answer which says all the above options are correct.

The phenomenon of resonance is explained by (a) molecular orbital theory (b) valence bond theory (c) neither of the two (d) both the above

Valence bond theory of chemical bonding was put forward initially by (a) Heisenberg (b) Einstein (c) Heitler and London (d) dc Broglie

Choose the incorrect answer: (a) Bonding MO are formed by the additive effect of the atomic orbitals. (b) The electron density in the internuclear region in bonding MO is very low. (c) Energy of the antibonding MO is higher than that of the combining atomic orbitals. (d) Antibonding MO are represented by \(\sigma^{*}, \pi^{*}, \delta^{*}\), etc.

The wave functions corresponding to ionic structures of hydrogen molecule, according to valence bond theory are (a) \(\psi_{A}(1) \psi_{B}(\mathrm{I}), \psi_{A}(2) \psi_{B}(2)\) (b) \(\psi_{A}(1) \psi_{A}(1), \psi_{B}(2) \psi_{B}(2)\) (c) \(\psi_{A}(2) \psi_{B}(2), \psi_{A}(1) \psi_{B}(1)\) (d) \(\psi_{A}(1) \psi_{A}(2), \psi_{B}(1) \psi_{B}(2)\)
