Answer to Question #313746 in Organic Chemistry for swarnajeet kumar

Question

Write chemical equation(s) for following conversions : i) Phenol to benzene ii) Ethylbenzene to 1-chloro-1-phenylethane iii) Aniline to chlorobenzene iv) Phenol to 4-hydroxybenzaldehyde v) Anisole to phenol

Answer 1

Phenol can be converted to benzene by using strong reducing agents like Zn dust with strong heating. When strongly heated,the phenol gets converted into phenoxide ion and proton thus released accepts an electron from Zn forming H radical.

2)

3)

Aniline to chlorobenzene conversion is shown in the above reaction. The reaction occurs via formation of benzene diazonium chloride.

4)

5)

Phenol when reacts with NaOH, it forms sodium phenoxide.This sodium phenoxide when reacts with ethyl bromide forms anisol as a product.
