Question

A) explain why carbon forms large number of compounds



b.Explain the formation of ethene by electron dot structure

Answer 1

a) Due to catenation it form large number of compounds

Answer 2

Carbon can form large no. Of compounds because:

1) Catenation
C compounds can combine with themselves to form long chains of carbon compounds.

2) Tetravalency
C has 4 valencies hence it could combine with 4 different atoms at the same time.

3) Small Size
C atom is small in size due to which it forms many compounds.

Electron dot structure is in the attachment :::::

Explaination:

The carbon atoms share 4 electrons and each carbon forms a single bond with two hydrogen atoms.

C2H4

H2C = CH2


H:C::C:H
