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

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
