Friedel-Craft's reaction using MeCl and anhydrous AlCl3 will take place most efficiently with
benzene
nitrobenzene
acetophenone
toluene
Under identical conditions, the SN1 reaction will occur most efficiently with
tert-butyl chloride
1-chlorobutane
2-methyl-1-chloropropane
2-chlorobutane
An equimolar mixture of toluene and chlorobenzene is treated with a mixture of conc.H2SO4 and cone. HNO3. Indicate the correct statement from the following.
p-nitrotoluene is formed in excess
equimolar amounts of p-nitrotoluene and p-nitrochlorobenzene are formed
p-nitrochlorobenzene is formed in excess
m-nitrochlorobenzene is formed in excess
Among the following carbocations:
Ph2C+CH2Me (I), PhCH2CH2CH+Ph (II),Ph2CHCH+Me (III) and Ph2C(Me)CH2 (IV), the order of stability is
IV > II > I > III
I > II > III > IV
II > I > IV > III
I > IV > III > II
The reaction of toluene with chlorine in presence of ferric chloride gives predominatly
benzoyl chloride
m - chlorotoluene
benzyl chloride
o- and p - chlorotoluene
D.
o- and p - chlorotoluene
Since, -CH3 group is o and p-directing group, so o-and p-chlorotoluene are obtained.
In benzene, the triple bond consists of
one sp-sp sigma bond and two p-p pi bonds
two sp-sp sigma bonds and one p-p pi bond
one sp2-sp2 sigma bond, one p-p pi bond
one sp2-sp2 sigma bond, one sp2-sp2 pi bond and one p-p pi bond

All of the above can be prepared
The product Y is
p-chloro nitrobenzene
o-chloro nitrobenzene
m-chloro nitrobenzene
o, p-dichloro nitrobenzene
