Question

explain why carbon forms compounds mainly by covalent bond explain in brief two main reasons for Carbon forming a large number of compounds.why does carbon form strong bonds with most other elements

Answer 1

Carbon forms Covalent Bond because of its TETRA VALANCY.
Tetra valancy : An element having 4 valancy.

And there are large number of carbon compound because of two reasons -
1. Tetra Valancy
2. Catination - Ability to form long carbon chains.

HOPE U UNDERSTAND IT

Answer 2

carbon is a tetravalent atom with the property of catenation.
thus, it forms compounds in which the carbon atom are arranged in the form of straight chains, branched chains or rings.
One more characteristics of carbon, which is responsible for large number of carbon compounds is Isomerism.
