Consider the following reaction sequence: 

 ${\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{CH}}_3\stackrel{\mathrm{Oxidation}}{\to }$ (A)  $\stackrel{\mathrm{NaOH}}{\to }$ (B) $\underset{∆}{\overset{\mathrm{Soda} \mathrm{lime}}{\to }}$ (C)

1.	C6H5OH	2.	C6H6
3.	C6H5COONa	4.	C6H5ONa

The reaction of toluene with ${\mathrm{Cl}}_2$ in the presence of ${\mathrm{FeCl}}_3$ 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

3-hexyne can be converted to trans-3-hexene by the action of:

1. ${\mathrm{H}}_2$ - Pd/ ${\mathrm{BaSO}}_4$                       2. Li-Liq. ${\mathrm{NH}}_3$

3. ${\mathrm{H}}_2$ - Pt ${\mathrm{O}}_2$                                4. ${\mathrm{NaBH}}_4$

CH₃-C$\equiv$C-H$\stackrel{{\mathrm{CH}}_3\mathrm{MgBr}}{\to }$CH₄ + (A)$\underset{\left(\mathrm{ii}\right) {\mathrm{H}}_2\mathrm{O}/{\mathrm{H}}^{+}}{\overset{\left(\mathrm{i}\right) {\mathrm{CO}}_2}{\to }}$(B); (B) will be

1. H₃C-CH₂-CH₂-COOH                                2. CH₃-C$\equiv$C-CH₃

3. H₃C-C$\equiv$C-COOH                                     4. H₃C-CH=CH-COOH

In Friedel-Craft's alkylation, besides AlCl₃, the other reactants are                             

1. C₆H₆ + NH₃

2. C₆H₆ + CH₄

3. C₆H₆ + CH₃Cl

4. C₆H₆ + CH₃COCl

1. Polyvinyl chloride                   

2. Allyl chloride  

3. 1-chloropropene   

4. 1,2-dichloroethane
