Which represents Riemer-Tiemann reaction?

An organic compound A reacts with PCl₃ to give B. The compound B with sodium metal in the presence of dry ether and gives n-butane. Thus, A and B are:

1. C₂H₅OH and C₂H₅Cl

2. C₂H₅Cl and C₂H₅ONa

3. C₃H₇OH and CH₃CH₂CH₂OCl

4. C₄H₉OH and C₄H₉OCl

Compound that is not an alcohol-

1. CH₂=CHCH₂OH                            

2. CH₂OHCH₂OH

3. C₆H₅CH₂OH                                 

4. C₆H₅OH

The boiling point of p-nitrophenol is higher than that of o-nitrophenol because -               

1. NO₂ group at p-position behaves in a different way from that at o-position.

2. Intramolecular hydrogen bonding exists in p-nitrophenol.

3. There is intermolecular hydrogen bonding in p-nitrophenol.

4. p-Nitrophenol has a higher molecular weight than o-nitrophenol.

The compound that generate methyl ethyl ketone upon oxidation is -

1. 2-Propanol                               

2. 1-Butanol

3. 2-Butanol                                 

4. tert-Butyl alcohol

3. 95.6 % alcohol                           4. 100.0% alcohol

The reaction of  with RMgX leads to the formation of                       

1. RCHOHR                               

2. RCHOHCH₃

3. RCH₂CH₂OH                         

4. ${}_{\mathrm{R}}{}^{\mathrm{R}}>{\mathrm{CHCH}}_2\mathrm{OH}$

Increasing order of acidic strength of

1. III, I, II             

2. II, I, III           

3. III, II, I         

4. I, II, III   

Ethers are not distilled to dryness for fear of explosion. This is due to formation of:

1. oxides                             

2. alcohol

3. ketones                           

4. peroxides
