A compound X with molecular formula C₃H₈O can be oxidised to a compound Y with the molecular formula C₃H₆O₂. X is most likely to be:

1. Primary alcohol                     

2. Secondary alcohol

3. Aldehyde                               

4. Ketone

The ionisation constant of phenol is higher than that of ethanol because -                   

1. Phenoxide ion is bulkier than ethoxide

2. Phenoxide ion is a stronger base than ethoxide

3. Phenoxide ion is stabilised through delocalisation

4. Phenoxide ion is less stable than ethoxide

The Williamson's synthesis reaction among the following is -

1.
2.

4.

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
