Chemistry Organic Chemistry questions from JEE Main 2003.
Among the following four structures I to IV.     It is true that
An ether is more volatile than an alcohol having the same molecular formula. This is due to
Bottles containing $\mathrm{C}_6 \mathrm{H}_5$ l and $\mathrm{C}_6 \mathrm{H}_5 \mathrm{CH}_2 \mathrm{I}$ lost their original labels. They were labelled $\mathrm{A}$ and $\mathrm{B}$ for testing $\mathrm{A}$ and $\mathrm{B}$ were separately taken in test tubes and boiled with $\mathrm{NaOH}$ solution. The end solution in each tube was made acidic with dilute $\mathrm{HNO}_3$ and then some $\mathrm{AgNO}_3$ solution was added. Substance B gave a yellow precipitate. Which one of the following statements is true for this experiment?
Butene- 1 may be converted to butane by reaction with

On mixing a certain alkane with chlorine and irradiating it with ultravioletlight, it forms only one monochloroalkane. This alkane could be
The correct order of increasing basic nature for the bases $\mathrm{NH}_3, \mathrm{CH}_3 \mathrm{NH}_2$ and $\left(\mathrm{CH}_3\right)_2 \mathrm{NH}$ is
The general formula $\mathrm{C}_{\mathrm{n}} \mathrm{H}_{2 \mathrm{n}} \mathrm{O}_2$ could be for open chain
The IUPAC name of $\mathrm{CH}_3 \mathrm{COCH}\left(\mathrm{CH}_3\right)_2$ is
The reaction of chloroform with alcoholic $\mathrm{KOH}$ and p-toluidine forms
The reason for double helical structure of DNA is operation of
