Which of the following amine will give primary alcohol with NaNO2?
Aliphatic primary amines react with NaNO2 and HCl to yield alcohols.
Which of the following reacts with NaNO2?
N-Methylaniline react with NaNO2 and dilute HCl at 0−5∘C to form.
Which of the following compounds gives alcohol?
Formaldehyde on reaction with Grignard reagent followed by acid hydrolysis gives primary alcohol.
Which of the following react with NaNO2 HCl to give phenol?
CH3NH2.
Which of the following compound gives alcohol with NaNO2 and HCl?
Which of the following compounds reacts with NaNO2 and HCl at -4°C to yield alcohol (OR) phenol? Solution: C2H5NH2 is an aliphatic primary amine, which reacts with NaNO2 and HCl at -4°C to yield alcohol (OR) phenol.
What does NaNO2 HCl do?
NaNO2+HCl is a very important reagent which can be used for the generation of the diazonium salts and used for further reactions.
Which of the following react with nano2 and HCl to form aryl diazonium salt?
The second key reagent is a strong mineral acid like HCl; if NaNO2 is used, HCl converts it into HNO2. The key purpose of HCl is to further convert HNO2 into the powerful electrophile NO+, the “nitrosonium ion“, which is the key electrophile in the reaction that forms the diazonium salt.
What test is used to distinguish phenol from alcohol?
Test to distinguish between alcohol and phenols
1. Litmus test : Phenols turn blue litmus red and alcohols have no effect. 2. Ferric chloride test : Phenols give blue, green, and violet color while alcohol give no change in color.
Which of the following is allylic alcohol?
Explanation: An example of an allylic alcohol is 2-methylbut-3-en-2-ol. If the hydroxyl group is attached to an allylic carbon atom [ce{C = C}], it is referred to as allylic alcohol.
Which of the following compounds gives a primary alcohol upon reaction with Methylmagnesium bromide?
7. Which of the following compounds gives a primary alcohol upon reaction with phenylmagnesium bromide? Explanation: Ethylene oxide reacts with Grignard reagents to give, after protonation, primary alcohols with two additional carbon atoms.
Which can give alcohol on reaction with?
Alcohols may be oxidized to give ketones, aldehydes, and carboxylic acids. These functional groups are useful for further reactions; for example, ketones and aldehydes can be used in subsequent Grignard reactions, and carboxylic acids can be used for esterification.
When benzene diazonium chloride is treated with cuprous chloride in HCl chlorobenzene is formed this reaction is called?
When benzene diazonium chloride in hydrochloric acid reacts with cuprous chloride, then chlorobenzene is formed. The reaction is called. The described reaction is Sandmeyer reaction.
When benzene diazonium chloride is treated with cuprous chloride and HCl the product formed is?

How is Bakelite obtained from phenol?
1) Bakelite is obtained by the condensation reaction of phenol with formaldehyde. … 4) After further polymerization of the intermediates in presence of formaldehyde, heat, and loss of water molecules will give the product as Bakelite.
