Q. No.Propanol has a higher boiling point than that of butane because -
1. Butane undergoes intermolecular ionic bonding
2. Propanol undergoes intermolecular H-bonding
3. Propanol undergoes intramolecular hydrogen bonding
4. Butane undergoes intermolecular H-bonding
The boiling point of ethanol is higher than that of dimethyl ether due to the presence of
| 1. | H-bonding in ethanol | 2. | H-bonding in dimethyl ether |
| 3. | -CH3 group in ethanol | 4. | -CH3 group in dimethyl ether |
The below-mentioned reaction can be classified as:
1. Alcohol formation reaction
2. Dehydration reaction
3. Williamson alcohol synthesis reaction
4. Williamson ether synthesis reaction
Alcohols are comparatively more soluble in water than hydrocarbons of comparable molecular masses because:
| 1. | Alcohols form van der waal bonds with water while hydrocarbons do not |
| 2. | Alcohols form covalent bonds with water while hydrocarbons do not |
| 3. | Alcohols form ionic bonds with water while hydrocarbons do not |
| 4. | Alcohols form H-bonds with water while hydrocarbons do not |
The formula for allyl alcohol is-
1. CH3-CH=CHOH
2. CH2=CHCH2OH
3. HOCH2CH2CH3
4. None of the above.
Propan-1-ol may be prepared by reaction of propene with -
1. CH3COOH
2. H3BO3

4. H2SO4/H2O
The IUPAC name of the above compound is:
1. 1-Phenylpropan-2-ol
2. 2-Phenylpropan-2-ol
3. 1-Phenylpropan-1-ol
4. 2-Phenylpropan-1-ol
The alcohol expected to have the lowest pKa value among the following is -
1. Ethanol
2. 2-Fluoro ethanol
3. 2,2,2-Trifluoroethanol
4. 2-Chloroethanol
Select the correct option based on statements below:
| Assertion (A): | p-Nitrophenol is more acidic than phenol. |
| Reason (R): | Nitro group helps in the stabilization of the phenoxide ion by dispersal of negative charge due to resonance. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | (A) is False but (R) is True. |
