In which year did Langmuir reform the Lewis concept by abandoning the idea of a stable cubical arrangement of the octet and introducing the term ‘covalent bond’?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 1919.
- Langmuir , in 1919 improved the Lewis concept by suggesting that when both the atoms taking part in a chemical combination are short of electrons than the nearest noble gas configuration , they can share their electrons in order to complete their octet.
- A covalent bond consists of the simultaneous attraction of two nuclei for one or more pairs of electrons. The electrons located between the two nuclei are bonding electrons.
