Arrange the following compounds in increasing order of their boiling points:
CH3CHO, CH3CH2OH, CH3OCH3, CH3CH2CH3
The correct sequence of increasing orders of reactivity in nucleophilic addition reaction is:
1. Butanone < Propanone < Propanal < Ethanal
2. Butanone > Propanone > Propanal > Ethanal
3. Butanone < Propanal < Propanone < Ethanal
4. Propanal < Propanone < Ethanal < Butanone
Arrange the following compounds in increasing order of their reactivity in nucleophilic addition reactions :Benzaldehyde, p-Tolualdehyde, p-Nitrobenzaldehyde, Acetophenone.
1. Acetophenone < Benzaldehyde < p-tolualdehyde < p-Nitrobenzaldehyde
2. Acetophenone < p-tolualdehyde < Benzaldehyde < p-Nitrobenzaldehyde
3. Acetophenone > p-tolualdehyde > Benzaldehyde < p-Nitrobenzaldehyde
4. Acetophenone < p-tolualdehyde < p-Nitrobenzaldehyde < Benzaldehyde
