An organic compound A reacts with sodium metal and forms B. On heating with conc. H2SO4, A gives diethyl ether. So A and B are:
1. C3H7OH and CH3ONa
2. CH3OH and CH3ONa
3. C4H9OH and C4H9ONa
4. C2H5OH and C2H5ONa
The reducing agent among the following is -
1. CrO3/H+
2. KMnO4
3. LiAlH4
4. O3
The structure of A in the below mentioned reaction is:
1. | 2. | ||
3. | 4. |
1. | \(\mathrm{NaBH}_4 \) | 2. | \(\mathrm{LiAlH}_4 \) |
3. | \(PCC \) | 4. | \(\mathrm{KMnO}_4\) |
The correct order of dehydration of compounds (i), (ii) and (iii) by conc. H2SO4 is:
(i) | |
(ii) | |
(iii) |
1. (i) > (iii) > (ii)
2. (i) > (ii) > (iii)
3. (ii) > (i) > (iii)
4. (ii) > (iii) > (i)
An aromatic compound A (C8H10O) gives the following tests with the given reagents.
The structure of 'A' is:
1. | 2. | ||
3. | 4. |
The strongest acid among the following aromatic compounds is -
1. | p-Chlorophenol | 2. | p-Nitrophenol |
3. | m-Nitrophenol | 4. | o- Nitrophenol |
Consider the following alcohols,
I. | |
II. | |
III. | |
IV. |
Ease of dehydration of the above alcohols will be in the order of-
1. | I < II < III < IV | 2. | I > II > III > IV |
3. | III < II < I < IV | 4. | II < III < IV < I |
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 |
