Question

1,3-dihydroxy phenol to 1-(2,4-dihydroxy phenyl ) ethanal

Answer 1

I don't understand your question.

Answer 2

• According to the question we have to produce 1-(2,4-dihydroxy phenyl ) ethanal from 1,3-dihydroxy phenol,

and when 1,3-dihydroxy phenol reacts with hydrochloric acid (HCl)and zinc cyanide [Zn(CN)2] and di-ethyl ether [Et2O] , it forms 1-(2,4-dihydroxy phenyl ) in 20°C

1,3-dihydroxy phenol——Zn(CN)2, Et2O,HCl,20°C —› 1-(2,4-dihydroxy phenyl )
