Question

1.Explain the unique nature of carbon atom with reference to a.Tetravalency b.Catenation​

Answer 1

Answer:

Some unique properties shown by carbon atom are : a Tetravalency b Catenation c Ability to form multiple bonds.Therefore carbon atom completes its octet by sharing four electrons with other atoms i.e. it can form four covalent bonds called its tetracovalency.

Answer 2

a) Tetravalency :- Atomic number of carbon is 6. Its electronic configuration is 2 4. Therefore it has four electrons in its valence shell. Carbon atom can neither lose nor gain electrons to complete its octet not possible from energy point of view.

b) Catenation:- The sigma bonds formed by the adjacent atoms in carbon is strong enough so that perfectly stabilized chains can be formed between the atoms. This is the reason why carbon exhibits the catenation property.
