Mark the compound that, when treated with NaNH₂, forms its sodium salt:
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 the reaction of toluene in the presence of light gives 'Y'. Hence, the products '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 chloride, 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
3-Hexyne can be converted to trans-3-Hexene by the action of:
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
In the reaction, A BC
the product C is:
