​

Answer 1

Answer:

A Ketone A(C

4

H

8

O) undergoes haloform reaction, So the Ketone should have −

∥

C

−CH

3

group.

O

So the structure of A is CH

3

−CH

2

−

∥

C

−CH

3

.

O

Now the reactions are :

A (butane−2−ene) on reduction gives butan−2−ol

(B) Which on heating with H

2

SO

4

gives a alkene named but−2−ene (C). C forms mono-ozonide D which on hydrolysis in presence Zn dust to form acetaldehyde (E).
