For carbon monoxide and … which statement is FALSE. Dilithium, Li2, is a strongly electrophilic, diatomic molecule comprising two lithium atoms covalently bonded together. Darren Herweyer. If the distribution of electrons in the molecular orbitals between two atoms is such that the resulting bond would have a bond order of zero, a stable bond … Robert. A molecule in which all the electrons are paired, is called diamagnetic while molecule which has one or more unpaired electron is called paramagnetic. Li2+ is more stable than Li2− because Li2− has more numbers of antibonding electrons. Answer to Draw a molecular orbital energy diagram for Li2. Dilithium, Li2, is a strongly electrophilic, diatomic molecule comprising two lithium atoms covalently bonded together. Explain why the relative energy levels diagrams for Li2, Be2, B2, C2, N2 are different The molecular orbital theory of Li2 … Bond order = 1/2 (#e- in bonding MO - #e- in antibonding MO) For H 2, bond order = 1/2 (2-0) = 1, which means H 2 has only one bond. Update: no i mean a Li^2+ charge... Answer Save. If you mean Li2 with a +1 charge, YES. Likewise Li2^- has an MO scheme of σ (↑↓) σ* (↑) and also a bond order of 0.5 and again should be observed in the gas phase. Therefore, Bond order of C2+ = 1/2 (5 - 2) = 3/2 = 1.5 Bond order of C2- = 1/2 (7 - 2) = 5/2 = 2.5 Bond order of C2 = 1/2 (6 - 2) = 2 Highest bond order means highest bond energy and shortest bond length. Let us help you simplify your studying. The most reliable of these potential energy curves are of the Morse/Long-range variety. In my opinion you are mistaken.

Determining the bond order starting from a Lewis structure is a task that can range from very easy to rather difficult. Use the drawing of the MO energy diagram to predict the bond order of Li2?. Each hydrogen atom contributes one electron, and thus, "H"_2^(-) has three electrons while "H"_2^(+) has one. [1] This problem has been solved! MOLECULAR ORBITAL PROBLEMS. (Use the … For example, the C3 value for atomic lithium extracted from the A-state potential of Li2 by Le Roy et al. Li2 is known in the gas phase. 0.5. diatomic molecules from Li2 to N2 is shown below. the greater the bond order for a bond between 2 atoms, the longer the length of the bond between them. 2. Stability of the species Li2 , Li2- , and Li2+ increases in the order of Q. The traditional chemical approaches, Lewis electron dot structures and molecular orbital theory, predict the relative bond orders of boron monofluoride, carbon monoxide, and dinitrogen to be BF < CO < N2. Bond order is defined as the number of electrons in bonding MOs (for H 2 this is two) minus the number of electrons in antibonding MOs (zero) divided by two. Use MO diagram to place C2-,C2 and C2+ in order of decreasing bond energy? Your email address will not be published. Li2 is known in the gas phase.
