Out of the two compounds shown below, the volatile nature of \(\mathrm{B}\) at a particular temperature is expected to be
1 higher than that of \(\mathrm{A}\)
2 lower than that of A
3 same as that of A
4 can be higher or lower depending upon the size of the vessel
Explanation:
Due to intramolecular \(\mathrm{H}\)-bonding in \(\mathrm{o}\) nitrophenol, it exists as a monomer while due to intermolecular \(\mathrm{H}\)-bonding in p-nitrophenol, it exists as an associated molecule. As a result, volatile nature of o-nitrophenol is higher than that of \(\mathrm{p}\)-nitrophenol.

Density of ice is less than that of water because of
1 Extensive hydrogen bonding
2 Crystal modification of ice
3 Open porous structure of ice due to hydrogen bonding
4 Different physical states of these
Explanation:

Which of the following is miscible with water?
1 \(\mathrm{CS}_{2}\)
2 \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\)
3 \(\mathrm{CCl}_{4}\)
4 \(\mathrm{CHCl}_{3}\)
Explanation:
\(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\) can form intermolecular \(\mathrm{H-}\) bonding with \(\mathrm{H}_{2} \mathrm{O}\), so miscible with water. (Rest cannot form hydrogen bonds with water).
