2-hexene

(i) O_{3} (ii) H_{2} O

Products

The two products formed in above reaction are -

(A)Butanoic acid and acetic acid✓ Correct
(B)Butanal and acetic acid
(C)Butanal and acetaldehyde
(D)Butanoic acid and acetaldehyde

Answer: (A)

Solution

2

-Hexene is

CH X_{3} CH = CHCH X_{2} CH X_{2} CH X_{3}

. Ozonolysis followed by a work-up with water, which generates hydrogen peroxide, cleaves the double bond oxidatively, so each doubly bonded carbon that carries a hydrogen is converted to a carboxyl group. The

CH X_{3} CH =

end gives acetic acid and the

= CHCH X_{2} CH X_{2} CH X_{3}

end gives butanoic acid. The two products are butanoic acid and acetic acid.
