Answer: In the given reaction, first benzyl alcohol is reacted with PCl5 to given benzyl chloride. Then this benzyl chloride is reacted with KCN to given benzyl cyanide. Finally, benzyl cyanide undergoes hydrolysis to form 2-phenylethanoic acid as a product.
How do you make benzyl cyanide?
Benzyl cyanide can be produced via Kolbe nitrile synthesis between benzyl chloride and sodium cyanide and by oxidative decarboxylation of phenylalanine. Benzyl cyanides can also be prepared by arylation of silyl-substituted acetonitrile.
How do you convert benzene to benzyl alcohol?
First, we will have to do Friedal crafts Alkylation to form Toluene. Then, toluene is oxidized with KMnO₄ and then reduced with LiAlH₄ to get Benzyl alcohol.
How will you bring about the following transformation benzyl bromide to benzyl cyanide?
Benzyl bromide is treated with potassium cyanide to get benzyl cyanide. First, benzyl bromide is treated with potassium hydroxide to give benzyl alcohol which on further reaction with acetic acid gives benzyl acetate. Bromoethane on reaction with sodium methanethiolate gives diethyl thioether.
How the following conversions can be carried out a benzyl alcohol to 2-phenylethanoic acid?
Benzyl alcohol to 2-Phenyl ethanoic acid. Conversion of benzyl alcohol to -2-phenyl ethanoic acid. Give the uses of Freon 12, DDT, carbon tetrachloride and iodoform. … Preparation: It is manufactured by the condensation of chlorobenzene with trichloro acetaldehyde (chloral) in the presence of sulphuric acid.
What is benzyl cyanide used for?
Applications. TCC’s Benzyl Cyanide (BnCN), C6H5CH2CN, is used in organic synthesis for dyes, perfumes, pesticides, and pharmaceuticals, especially penicillin precursors. BnCN is an important intermediate for a variety of useful, and sometimes dangerous, compounds.
Is benzyl cyanide poisonous?
A skin, eye, and mucous membrane irritant, possibly burning skin and eyes; Toxic by inhalation, ingestion, and skin absorption; [CAMEO] Highly toxic; Oral LD50 (mouse) = 45.5 mg/kg; Skin LD50 (rat) = 2000 mg/kg; [MSDSonline] See “NITRILES.”
Are benzene and benzyl alcohol the same?
Benzyl alcohol is an aromatic alcohol that consists of benzene bearing a single hydroxymethyl substituent. It has a role as a solvent, a metabolite, an antioxidant and a fragrance. Benzyl alcohol is a Pediculicide.
How the following conversions can be carried out benzyl chloride to benzyl alcohol?
If benzyl chloride is treated with NaOH (followed by acidification) then benzyl alcohol is produced.
Will benzyl chloride convert to benzyl alcohol?
Answer: The compound with a group -CH2Cl attached to the benzene ring is benzoyl chloride, and the compound with a group -CH2OH attached to the benzene ring is benzoyl alcohol. Benzyl chloride undergoes a substitution reaction when reacting with aqueous potassium hydroxide to give benzyl alcohol.
How is benzyl chloride converted into phenyl Etnanolic acid write the reaction?
First benzyl alcohol is reacted with PCl5 to given benzyl chloride. Then this benzyl chloride is reacted with KCN to given benzyl cyanide. Finally, benzyl cyanide undergoes hydrolysis to form 2-phenylethanoic acid as a product.
How do you convert toluene to benzyl alcohol?
The conversion of toluene into benzyl alcohol can be achieved in two steps. Free radical chlorination of toluene with chlorine in presence of ultraviolet light or heat give benzyl chloride. One hydrogen atom of methyl group of toluene is replaced with chlorine atom. A molecule of hydrogen chloride is eliminated.
How is benzoyl chloride converted into phenyl Ethanoic acid write the reaction?
After this benzyl cyanide undergoes the process of hydrolysis and forms the final product i.e. 2-phenyl ethanoic acid. … In this way Benzyl alcohol gets converted into 2-phenyl ethanoic acid.
How the following conversions can be carried out 2 Chlorobutane to 3/4 Dimethylhexane?
When 2-chlorobutane is treated with solid sodium in the presence of dry ether, it results in the formation of 3, 4-dimethylhexane. This reaction above is known as Wurtz reaction. This reaction occurs when one has to increase carbon atoms. In this, two moles of sodium halide is released.
How the following conversion can be carried out ethanol to but 2 YNE?
(i) Ethanol to But$ – 2 – $yne – To convert ethanol to but$ – 2 – $yne by following order of reactions. First of halogenation of ethanol will be performed with $P/B{r_2}$,then dehydrohalogenation reaction. After that electrophilic substitution will be done. … This reaction is carried out with $NaI$ and acetone.
How the following conversions can be carried out 2 Chloropropane to 1 propanol?
So we cannot carry out a substitution reaction directly for the formation of 1- propanol from 2- chloropropane. First we convert the 2- chloropropane into a haloalkane with the halogen molecule attached at the terminal carbon atom. To do this, react the given compound with an alcoholic solution of KOH .
