Question

HCl is in the form of liquid or gas in groove's process? ​

Answer 1

Explanation:

Grooves process=

It is the process to synthesize alkylhalide from alcohol using ZnCl₂.

The reaction can be written as:

Anhyd ZnCl₂

R --- OH + H---X ========>> RX + H₂O

The reactivity order of in the above reaction is : HI > HBr > HCl > HF

Reactivity order of alcohols = 3⁰ > 2⁰ > 1⁰ > MeOH

2⁰ and 3⁰ alcohols undergo SN₁ mechanism, whereas 1⁰ and MeOH undergo SN₂ mechanism. Concentrated HCl + anhy. ZnCl₂ is known as lucas reagent. In Groove's process, ZnCl₂ is used to weaken C-OH bond. In case of 3⁰ alcohol, ZnCl₂ is not required.

Example =

Anhyd ZnCl₂

C₂H₅OH + HCl ===========>> C₂H₅Cl + H₂O
