The correct order of boiling point in the following compounds is

The number of hydrogen bonds formed by a water molecule at normal conditions is

Which of the molecules does not show hydrogen bonding?

Which one of the following compounds shows the presence of intramolecular hydrogen bond ?

Intramolecular hydrogen bonding is present in:

Which of the following is arranged in the increasing order of enthalpy of vaporisation?

Which of the following is arranged in the increasing order of enthalpy of vaporisation ?

With respect to the boiling point for the substances ${\mathrm{H}}_2\mathrm{O}, {\mathrm{NH}}_3, \mathrm{CsF}$ and $\mathrm{He}$, the correct order is:

Among the following, the molecule with minimum melting point is

Determine the appropriate order of the strength of $\mathrm{H}$-bonds.

Dimethyl ether have boiling point less than ethanol though they have the same molecular weight. This is due to:

The hydrogen bond will have maximum strength in-

$\mathrm{p}-$Nitrophenol has greater boiling point than that of $\mathrm{o}-$nitrophenol. What is the reason?

The strongest hydrogen bond is:

Hydrogen bonding is seen in:

Amongst ${\mathrm{H}}_2\mathrm{O}, {\mathrm{H}}_2\mathrm{S}, {\mathrm{H}}_2\mathrm{Se} \mathrm{and} {\mathrm{H}}_2\mathrm{Te},$the one with the highest boiling point is:

The amines given are isomers. Choose the one with the lowest boiling point.

The maximum possible number of hydrogen bonds which ${\mathrm{H}}_2\mathrm{O}$ molecule can form is:
