A compound is treated with NaNH2 to give sodium salt. Identify the compound.
1. C2H2 2. C6H6
3. C2H6 4. C2H4
+ X
The product X in the above reaction is -
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
1. X= benzal chloride, Y=o-chlorotoluene
2. X=m-chlorotoluene, Y=p-chlorotoluene
3. X=o and p-chlorotoluene, Y= trichloromethyl benzene
4. X= benzyl hloride, Y=m-chlorotoluene
In Friedel-Craft's synthesis of toluene, the reactants in addition to anhydrous AlCl3 are
1. C6H5Cl + CH4
2. C6H5Cl + CH3Cl
3. C6H6 + CH4
4. C6H6 + CH3Cl

1. - Pd/
2. Li-Liq.
3. - Pt
4.
A compound having the shortest carbon-carbon bond length among the following is :
1. Benzene
2. Ethene
3. Ethyne
4. Ethane
Reaction of HBr with propene in the presence of peroxide gives
1. iso-propyl bromide
2. 3-bromo propane
3. allyl bromide
4. n-propyl bromide
The reaction of toluene with in the presence of gives 'X' and reaction in presence of light gives 'Y'. Thus, 'X' and 'Y' are
1. X = benzal chloride, Y= o-chlorotoluene
2. X = m-chlorotoluene, Y= p-chlorotoluene
3. X = o and p-chlorotoluene, Y = trichloromethyl benzene
4. X = benzal chloride, Y = m-chlorotoluene
