Friedel-Craft's reaction using MeCl and anhydrous AlCl3 will take place most efficiently with:
benzene
nitrobenzene
acetophenone
toluene
D.
toluene
Friedel-crafts reaction is an electrophilic substitution reaction and presence of an electron releasing substituent like Me, makes the benzene nucleus more reactive towards such reactions)
Thus toluene is most reactive among the given.
The ease of nitration of the following three hydrocarbons follows the order:
II = III = I
II > III > I
III > II > I
I = III > II
Among the alkenes which one produces tertiary butyl alcohol on acid hydration?
CH3-CH2-CH=CH2
CH3-CH=CH-CH3
(CH3)2C=CH2
CH3-CH=CH2
Nitrobenzene on reaction with conc. HNO3/H2SO4 at 80-100°C forms which one of the following products?
1, 2-dinitrobenzene
1, 3-dinitrobenzene
1, 4-dinitrobenzene
1, 2, 4-trinitrobenzene
Some meta-directing substituents in aromatic substitution are given. Which one is most deactivating?

6p-orbitals and 6 unpaired electrons
7p-orbitals and 6 unpaired electrons
7p-orbitals and 7 unpaired electrons
6p-orbitals and 7 unpaired electrons
Which of the following compounds will not undergo Friedal-Craft's reaction easily?
