Question

22. Draw diagrams showing the formation of a double bond and a triple bond between carbon
atoms in C
​

Answer 1

Explanation:

Answer

In ethylene, the carbon atom is sp

2

hybridized.

In acetylene, the carbon atom is sp hybridized.

The energy level diagrams of ethylene and acetylene are shown below.

Answer 2

Answer:

C2H4 : The electronic configuration of C-atom in the excited state is: In the formation of an ethane molecule (C2H4), one sp2 hybrid orbital of carbon overlaps a sp2 hybridized orbital of another carbon atom, thereby forming a C-C sigma bond. The remaining two sp2 orbitals of each carbon atom form a sp2 -s sigma bond with two hydrogen atoms. The unhybridized orbital of one carbon atom undergoes sidewise overlap with the orbital of a similar kind present on another carbon atom to form a weak n-bond.
