What happens when chlorobenzene treated with KNH2 in presence of liquid NH3?
ANSWER. p-Chlorotoluene first gives benzyne with methyl as substituent. When -NH2 attacks at carbon which is bearing triple bond it gives mixture of meta and para-toluidine. Major product is m-toluidine because carbanion formed at meta position by attack of nucleophile is more stable comapre to para position.
Is KNH2 a base?
Potassium amide is an inorganic compound with the chemical formula KNH 2. Like other alkali metal amides, it is a white solid that hydrolyzes readily. It is a strong base.
Which of the following compounds is the major product when O chlorotoluene?
The major products formed in the reaction of toluene with chlorine in the presence of ferric chloride are o-chlorotoluene and p-chlorotoluene. Was this answer helpful?
Why is KNH2 a base?
The basic property of both KOH and KNH2 is due to their anionic part i.e., -OH and -NH2 respectively (both having -1 charge). Now bases, upon reception of a proton forms conjugate acids. Water (H2O) is the conjugate acid of -OH and ammonia (NH3) is the conjugate acid of -NH2.
What product may be formed when chlorobenzene is reacted with sodium hydroxide using water as the solvent?
An early method of preparing phenol (the Dow process) involved the reaction of chlorobenzene with a concentrated sodium hydroxide solution at temperatures above 350 ºC. The chief products are phenol and diphenyl ether (see below).
Which reaction do we use for the preparation of p-Chlorotoluene?
p-Chlorotoluene can be prepared by the action of chlorine5 and of sulfuryl chloride6 on toluene in the presence of various catalysts, and by the diazo reaction with p-toluidine. This preparation is referenced from: Org.
What is the name of KNH2?
Potassium amide
Potassium amide | KNH2 – PubChem.
Which of the following compounds is the major product when O chlorotoluene reacts with Sodamide in presence of ammonia?
Major product is m-toluidine because carbanion formed at meta position by attack of nucleophile is more stable comapre to para position.
Which is major product ortho chlorotoluene or para chlorotoluene?
But, because of steric hindrance at the ortho position, the para-product usually predominates over the ortho product.So 4-chloro toluene or para chloro toluene predominates over ortho chloro toluene. Hence option C is correct.
Which reaction do we use for the preparation of p-chlorotoluene?
What happens when ch3cooh is dissolved in liq NH3?
Ethanoic acid reacts with ammonia in exactly the same way as any other acid does. It transfers a hydrogen ion to the lone pair on the nitrogen of the ammonia and forms an ammonium ion. If you mix together a solution of ethanoic acid and a solution of ammonia, you will get a colorless solution of ammonium ethanoate.
What happens when chlorobenzene react with ammonia?
Under high pressure and at high temperature, chlorobenzene reacts with water or with ammonia, which displace the chlorine atom and form phenol or aniline.
When chlorobenzene is treated with Sodamide and liq nh3 the product is?
aniline
Chlorobenzene reacted with the very strong base sodium amide NaNH2 at low temperature −33oC in liquid ammonia to give aniline (aminobenzene).
How is toluene converted to ortho and para Chlorotoluene?
Answer. Answer: To convert the Toluene to para-chlorotoluene, You need to perform friddle craft alkylation reaction.
Which of the following is the major product when p-Chlorotoluene reacted with Sodamide in presence of ammonia?
m-toluidine
Major product is m-toluidine because carbanion formed at meta position by attack of nucleophile is more stable comapre to para position.
Which reaction do we use for the preparation of P chlorotoluene?
