The introduction of an electron-rich or electron-deficient species to a carbon chain results in the formation of a permanent dipole. This effect is called the inductive effect. write and Explain What do you know about the word Infallible?
Answers
Answer:
(i) Electron deficient compounds of hydrogen do not have sufficient number of electrons to form normal covalent bonds. Examples include hydrides of group 13 such as BH
3
,AlH
3
etc. They exist in polymeric forms such as B
2
H
6
,Al
2
H
6
. Thus, they make up their deficiency.
(ii) Electron precise compounds of hydrogen contain sufficient valence electrons to form covalent bonds. Examples include group 14 hydrides CH
4
,SiH
4
,GeH
4
,SnH
4
,PbH
4
etc. These compounds have tetrahedral shape.
(iii) Electron rich compounds of hydrogen contain excess valence electrons to form covalent bonds.
Examples include group 15 and group 17 hydrides such as NH
3
,PH
3
,HCl,HBr etc. These compounds contains lone pairs of electrons.
Answer:
Infallible means never failing.
