2. CH₃OH and CH₃ONa
3. C₄H₉OH and C₄H₉ONa
4. C₂H₅OH and C₂H₅ONa

Which of the following factors is responsible for the higher boiling point of ethanol compared to dimethyl ether?

The best reagent to convert pent-3-en-2-ol into pent-3-en-2-one is:

1. Acidic KMnO₄

2. Alkaline K₂Cr₂O₇

3. Chromium anhydride in glacial acetic acid

4. Pyridinium Chlorochromate

Given is a reaction for your reference:

\(CH_3CH_2CH_2OH \xrightarrow[160\ - \ 180 ^\circ C]{Conc.\ H_2SO_4}\ X\ \xrightarrow{Br_2}\ Y\)
