Interpretation:
An energy diagram for the molecular orbitals of period 2 diatomic molecules should be drawn and the difference in ordering for B2, C2 and N2 should be compared to O2, F2 and Ne2.
Concept introduction:
MOT is more accurate theory than
(i) The molecular orbitals are formed by the linear combination of atomic orbitals. There are two type of combination (a) constructive (b) destructive interference
(ii)Molecular orbitals formed by constructive interference is known as bonding molecular orbital, and its energy is less than atomic orbital
(iii) Molecular orbital formed by destructive interference is known as anti bonding molecular orbital and its energy is greater than atomic orbital.
(iv) Electrons in molecular orbitals are filled according to Aufbau’s rule, Pauli’s Exclusion Principle, and Hund’s rule.

- In the molecular orbital mode l, compare and contrast bonds with bonds. What orbitals form the bonds and what orbitals form the bonds? Assume the z-axis is the internuclear axis.arrow_forwardWhich of the following molecules or ions are para-magnetic? What is the highest occupied molecular orbital (HOMO) in each one? Assume the molecular orbital diagram in Figure 9.16 applies to all of them. (a) NO (b) OF (c) O22 (d) Ne2+arrow_forwardTrue or false: Boron contains 2s22p1 valence electrons, so only one p orbital is needed to form molecular orbitals.arrow_forward
- Give the hybridization of each central atom in the following molecules. (a) cyclohexene (b) phosgene, Cl2CO (c) glycine, H2NC(1)H2C(2)OOH (Note: Numbers in parentheses label each carbon atom.)arrow_forwardThe bond length in C2 is 131 pm. Compare this with the bond lengths in C2H2 (120 pm), C2H4 (134 pm), and C2H6 (153 pm). What bond order would you predict for C2 from its bond length? Does this agree with the molecular orbital configuration you would predict for C2?arrow_forwardSpecify the electron-pair and molecular geometry for each underlined atom in the following list. Describe the hybrid orbital set used by this atom in each molecule or ion. (a) CSe2 (b) SO2 (c) CH2O (d) NH4ssarrow_forward
- The molecular orbital diagram of NO shown in Figure 10.47 also applies to the following species. Write the molecular orbital electron configuration of each, indicating the bond order and the number of unpaired electrons. (a) CN (b) CO (c) BeB (d) BC+ Figure 10.47 Molecular orbital diagram for nitric oxide (NO). The molecular orbital diagram for NO predicts a bond order of 2.5 and predicts that the molecule is paramagnetic with one unpaired electron. These predictions are verified by experimental measurements.arrow_forwardThe compound sketched below is acetylsalicylic acid, commonly known as aspirin. (a) What are the approximate values of the angles marked A, B, C, and D? (b) What hybrid orbitals are used by carbon atoms 1, 2, and 3ss?arrow_forwardDetermine the bond order of each member of the following groups, and determine which member of each group is predicted by the molecular orbital model to have the strongest bond. (a) H2,H2+,H2 (b) O2,O22+,O22 (c) Li2,Be2+,Be2 (d) F2,F2+,F2 (e) N2,N2+,N2arrow_forward
