3,3-dimethylbutan-2-ol losses a molecule of water in the presence of concentrated sulphuric acid to give tertramethylethylene as a major product. Suggest a suitable mechanism.

A : When 3,3-dimethyl butan - 2 - ol is heated in presence of concentrated H_(2)SO_(4) then 2, 3-dimethyl but -2-ene is formed as major product . R : In this reaction , carbocation is formed as an intermediate

What happens when hot and concentrated sulphuric acid reacts with the following: NaNO_3

The major product formed when a 3-methyl butan-2-ol is heated with concentrated sulphiric acid, is :

Name the product when sulphur trioxide is dissolved in concentrated sulphuric acid. Give the equation also.

The product formed when ethene gas reacts with water in the presence of sulphuric acid is______ (ethanol/ethanal/ethanoic acid)

State true or false Sulphuric acid formula is [H2SO3].

(i) An organic compound A with molecular formula C_(7)H_(8) on oxidation by chromyl chloride in the presence of C Cl_(4) gives a compound B which gives positive Tollen's test. The compound B on treatment with NaOH followed by acid hydrolysis gives two product C and D. C on oxidation gives B which on further oxidation gives D. the compound D on distillation with sodalime gives a hydrocarbon E. Below 60^(@)C , concentrated nitric acid reacts with E in the presence of concentrated sulphuric acid forming a compound F. identify the compounds A,B,C,D,E and F. (ii) Give chemical test to distinguish : Formaldehyde and acetaldehyde.

When 3,3- dimethyl -2- butanol is heated with H_(2)SO_(4) the major product obtained is

3 -Phenylpropene on reaction with HBr gives (as major product)
