Answer 2

Answer:

1) Butanal and Ethanal

2) 3-pentanone and Methanal

Explanation:

On ozonolysis, $O_{3}$ breaks the unsaturated bonds of alkenes, alkynes, azos to give different products.

In this reaction, we add Zinc (dust) and water to obtain acetaldehyde and formaldehyde.

• (1) Ozonolysis in Hex-2-ene

⇒ $CH_{3}-CH_{2}-CH_{2}-CH_{}=CH_{}- CH_{3}$ + $O_{3} +Zn_{}+H_{2}O$→$CH_{3}-CH_{2}-CH_{2}-CHO+CH_{3}-CHO_{}$

Butanal and Ethanal are formed.

• (2) Ozonolysis in 2-Ethyl but-1-ene​

⇒$CH_{3}-CH_{2}-C(CH_{2}-CH_{3} })=CH_{2}+O_{3}+ Zn+H_{2}O$ → $CH_{3}-CH_{2}-C(O)-CH_{2}-CH_{3}+CH_{2}O$

3-pentanone and Methanal are formed.

Conclusion:

Butanal and Ethanal are formed by ozonolysis of Hex-2-ene.

3-pentanone and Methanal are formed by ozonolysis of 2-Ethyl but-1-ene​.
