Question

(a)Explain why carbon forms covalent bond?
Give two reasons for forming a large number of compounds.
(b) Write the structural formula of ethane.
​

Answer 1

(a) A chemical bond is an attractive force that holds the atoms the atoms together in a molecule or compound. The element carbon in known to have the unique ability to from bonds with other similar atoms or atoms of other elemtents. This property of carbon has resulted in its having very large number of compounds.

(b) C2H6

Answer 2

Answer:

(a) carbon compounds forms covalent bonds because of its tetravalency , it can neither gain or lose electrons (because it requires large amount of energy to gain or lose 4 electrons) so it shares them.

(b) Ethane/Formula

C2H6

Image result for Write the structural formula of ethane.

Ethane is a colorless, odorless, and flammable gas with a chemical formula of C2H6; it has two carbon (C) atoms and six hydrogen (H) atoms.
