The product of the reaction between
(1) (2) (3) (4)
The reaction of toluene with Cl2 in the presence of FeCl3 gives 'X' and reaction in presence of presence of light gives 'Y'. Thus 'X' and 'Y' are
(a) X= benzal chloride, Y=o-chlorotoluene
(b) X=m-chlorotoluene, Y=p-chlorotoluene
(c) X=o and p-chlorotoluene, Y= trichloromethyl benzene
(d) X= benzyl hloride, Y=m-chlorotoluene
What products are formed when the following compound is treated with Br2 in the presence of FeBr3?
In Friedel-Craft's alkylation, besides AlCl3 the other reactants are
(a) C6H6 + NH2
(b) C6H6 + CH4
(c) C6H6 + CH3Cl
(d) C6H6 + CH3COCl
(c) Friedel-Craft's alkylation When benzene reacts with alkyl halide in presence of anhy. AlCl3, toluene is obtained. It is called Friedel-Craft's alkylation. Friedel-Craft's reaction is type of electrophilic substitution.
C6H6 + CH3Cl C6H5CH3 + HCl
Benzene reacts with n-propyl chloride in the presence of anhydrous AlCl3 to give
(b) n-propyl benzene
(c) no reaction
(d) iso-propyl benzene
In a set of reactions, ethyl benzene yielded a product D.
(d) Alkaline KMnO4 converts complete carbon chain that is directly attached to benzene nucleus, to -COOH group. Br2 in the presence of halogen carrier causes bromination by electrophilic substitution reaction and ethyl alcohol in acidic medium results in esterification.
In Friedel-Craft's synthesis of toluene, the reactants in addition to anhydrous AlCl3 are
(a) C6H5Cl + CH4
(b) C6H5Cl + CH3Cl
(c) C6H6 + CH4
(d) C6H6 + CH3Cl
In Friedel-Craft's synthesis of toluene, the reactants in addition to anhydrous are
(d) Friedel-Craft's alkylation of benzene (Ar-H) Mechanism of this reaction is represented as follows :
+ + + HCl
Thus, and are required in addition to .
In the reaction, A BC
the product C is:
Xylene on oxidation with acidic gives:
(a) phthalic acid (b) isophthalic acid
(c) terephthalic acid (d) all of these
