9.8 What do you understand by (i) electron-deficient, (ii) electron-precise, and (iii) electron-rich compounds of hydrogen? Provide justification with suitable examples.
Those compounds having fewer electrons to writing its conventional Lewis structure. examples (all the elements of group 13 form electron deficient hydrides)
Those compounds have the required number of electrons to write their conventional Lewis structure. ex- (all elements of group 14 form such compounds)
Electron-rich hydrides have excess electrons which are present as lone pairs. elements of group 15-17 form such compounds like has one lone pair and two lone pair respectively.
