Question
What do you understand by electron-precise? Provide justification with a suitable example.
Solution
Molecular hydrides are classified on the basis of the presence of the total number of electrons and bonds in their Lewis structures as:
Electron-precise hydrides:
An electron-precise hydride has a sufficient number of electrons to be represented by its conventional Lewis structure e.g. CH4. The Lewis structure can be written as:
Four regular bonds are formed where two electrons are shared by two atoms.
