Question

What is isomerism ?


(See the attachment , what about this ?)​

Answer 1

$\huge\bf{Answer :}$

✥ Isomerism is the property in which more than one compounds containing same chemical formula possesses different chemical structures.

⇒ The isomers are those chemical compounds that contains similar chemical formula but varies in the arrangement of atoms and chemical properties.

$\huge\bf{Extra\: Information :}$

⇒ Carbon contains 4 electrons in it's outermost shell ( or valence shell ) . So , it would either lose or gain 4 electrons to attain the inert gas configuration or stable configuration.

• It is very difficult for a tiny atom of Carbon to accept another 4 electrons to form C-⁴ anion having 4 extra electrons. Also , due to strong force of repulsion , it would be difficult for the nucleus with 6 protons to hold 10 electrons ( i.e 4 extra electrons ).
• The removal of 4 electrons from the valence shell of the carbon atom would deal with large amount of energy . So , carbon cannot form a C+⁴ cation , leaving behind a carbon cation with 6 protons in it's nucleus.
• Therefore , carbon solves this difficulty by sharing it's 4 valence electrons with the other carbon atoms or shares it's valence electrons with the atoms of other elements. This is known as the tetravelency of the carbon.
