The alkene that will give the same product with HBr in the absence as well as in the presence of peroxide is
2-butene
1-butene
propene
2-methylpropene
Chlorination of benzene in the presence of halogen carrier is an example of
aromatic nucleophilic substitution
aromatic electrophilic substitution
aromatic nucleophilic addition
aromatic electrophilic addition
For preparing an alkane, a saturated solution of sodium or potassium salt of a carboxylic acid is subjected to
hydrolysis
electrolysis
oxidation
hydrogenation
The reaction of with HBr gives predominantly
A.
The addition of HBr to an alkene is an example of electrophilic addition reactions. It takes place by following mechanism.
An organic compound with molecular formula C6H12 upon ozonolysis give only acetone as the product. The compound is
2,3-dimethyl-1-butene
3-hexane
2-hexene
2,3-dimethyl-2-butene
An alkene having the molecular formula C9H18 on ozonolysis gives 2, 2-dimethyl propanal and 2-butanone. The alkene is :
2, 2, 2-trimethyl-3-hexene
2, 2, 6-trimethyl-3-hexane
2, 3, 4-trimethyl-2-hexene
2, 2, 4-trimethyl-3-hexene
Observe the following reactions and predict the nature of A and B:
A and B both are
A and B both are
A is and B is
A is and B is
Nitration of aniline in strongly acidic medium, result in the formation of m-nitroaniline also. This is because :
amino group is meta orienting during electrophilic substitution reaction
nitro group goes always to the meta position irrespective of the substituents
nitration of aniline is a nucleophilic substitution reaction in strongly acidic medium
in strongly acidic conditions aniline is present as anilinium ion
