Predict whether He2+ exist?

Short Answer

Expert verified

Yes, He2+does exist.

Step by step solution

01

Understanding bonding and anti-bonding molecular orbitals

In MO diagrams, the orbital with less energy that assists in bonding are known as bonding molecular orbitals. They are more stable than individual atomic orbitals as it senses more nuclei.

The orbitals with comparatively higher energy that detract from bonding are known as anti-bonding molecular orbitals. They are less stable with less electron density between the nuclei.

02

Understanding the existence of He2+

In the case of He2 molecule, there are a total of 4 electrons two occupying the bonding MO and the other two occupying anti-bonding MO thus canceling the stability gained by the electrons in the bonding MO. Hence, does not exist. On the other hand, in the case of,He2+ two electrons occupying the bonding MO and only one electron occupying the anti-bonding MO thus giving it net stability. Therefore,He2+ exists.

Most popular questions from this chapter

Use the symbol 未+and 未+to show the direction of polarity of the indicated bonds in each of the following compounds:

a. Draw two Lewis structures for C2H6O.

b. Draw three Lewis structures for C3H8O.

(Hint:The two Lewis structures in part a are constitutional isomers鈥攎olecules that have the same atoms but differ in the way the atoms are connected. The three Lewis structures in part b are also

constitutional isomers.)

An unknown disaccharide gives a positive Tollens鈥� test. A glycosidase hydrolyzes it to d-galactose and d-mannose. When the disaccharide is treated with methyl iodide and Ag2O and then hydrolyzed with dilute HCl, the products are 2,3,4,6-tetra-O-methylgalactose and 2,3,4-tri-O-methylmannose. Propose

a structure for the disaccharide.
