Question

HELP REQUIRED
(a) Predict the product A and B.
CH3-CH=CH2+O3----->A + Zn ----------->B
(b) Write the geometrical isomers of but-2- ene​

Answer 1

Answer:CH2=CH2

Explanation:

Answer 2

(a) A is propene ozonide and B is Ethanal and formaldehyde.

(b) The geometrical isomers of but-2- ene​ are trans-But-2-ene and cis-But-2-ene.

- The given reaction is ozonolysis of Propene.

- It can be depicted as follows:

CH₃-CH=CH₂ + O₃ → CH₃-CH-(O)(O₂)-CH₂ + Zn → CH₃CHO + HCHO

- But-2-ene has two geometric isomers:

1. Cis-but-2-ene : In this isomer, the 2 methyl groups are present on same side of the double bond.

2. Trans-but-2-ene : In this isomer, the 2 methyl groups are present on opposite side of the double bond.
