Explain why cleavage of phenyl alkyl oth...

Explain why cleavage of phenyl alkyl others with HBr always produces phenol and alkyl bromide A and not bromobenzone and allanols.

Text Solution

Verified by Experts

This is because during the reaction, the attack of halide ion cours to the protonated ether. Due to sterichindrance of bulky phenyl group, the attack cecurs preferably to the allyl group forming alkyl bromide.

Assertion : When Alkyl aryl ethers react with excess of hydrogen halides, phenol and Alkyl halide are produced. Reason: Alkyl aryl ethers are cleaved at the Alkyl-oxygen bond due to more stable Aryl-oxygen bond.

Carbon-oxygent bond in ethers can be cleaved b halogen acids, sulphuric acid, phosphorus pentachlodie, etc. The cleavage of C-O bond take place under drastic conditions with excess of hydrogen halides. R-O-R+2HX rarr 2RX +H_(2)O If hydrogen halide is not taken in excess then a molecule of alcohol and alkyl halide are formed. R-O-R+HI overset(373K) (rarr) R-OH+R-I The order of reactivity of hydrogen halides towards the given reaction depends on the bond strength of halogenated acids, weaker is the H-X bond, greter is its reactivity. In case of unsymmetrical ethers, the site of cleavage is such that the halide is formed from the alkyl group which is smaller in size. However, when one of the alkyl group is tertiary, the halide formed is the tertiary halide. Indiate wheterh the following statements // reactions are true or false. Alkyl aryl ethers react with HI to give phenol and alkyl halide. (a) True (b) False

A single alkene is produced when an alkyl bromide reacts with sodium ethoxide and ethanol. This alkene undergeoes hydrogenation and produces 2 - methyl butane . What is the identity of the alkyl bromide ?

Alcohols donot react with NaBr but when H.SO, is added they form alkyl bromides. Explain.
