Question

Explain the ozonolysis of But-2-ene with chemical equation

Answer 1

Answer:

2 molecule of ethanal.

Explanation:

Reaction of Ozonolysis of But-2-ene (alkene):

CH₃----- CH=CH----CH₃   -------------------> CH₃----- CHO + CH₃----- CHO                  

                   O

                  /     \          (O₃)

                 /       \

                O       O

On reaction of ozone with but 2 ene, it gives 2 molecule of ethanal.

If the alkene is symmetrical, the product is aldehyde.

If the alkene is unsymmetrical, the product is aldehyde and ketone.

Answer 2

$CH_3-CH=CH-CH_3 + [O_3]$ → $CH_3-CHO + CH_3-CHO$ 

Explanation:

Ozonolysis of But-2-ene gives 2 molecules of ethanal.

The chemical equation for ozonolysis of But-2-ene (alkene) is as follows -

Reactants used are

• But-2-ene
• Ozone

The product formed is -

• Ethanal (2 molecules)

$CH_3-CH=CH-CH_3 + [O_3]$ → $CH_3-CHO + CH_3-CHO$      

∴ The reaction of ozone with but-2-ene yields 2 molecules of ethanal.

An aldehyde is obtained as a product if the alkene used is symmetrical.

A ketone is obtained as a product if the alkene used is unsymmetrical.
