the questions of effects hydrogen bond of boiling point

The boiling point of liquid is raised by increasing the pressure and reduced by lowering the pressure. It can be demonstrated by the apparatus shown in figure...

Aldehydes and Ketones have relatively high boiling point as compared to hydrocarbons of comparable molecular masses. This is because the aldehydes and ketones contain polar carbonyl group and therefore have stronger intermolecular dipole dipole interactions between the opposite..

Hydrogen bonding has important effect on many physical properties of compounds, described bel..

Amines are polar compounds and have higher boiling points than non-polar compounds such as hydrocarbons of some molecular mass. All amines can form hydrogen bonds as protons acceptors by coordination with the lone pair of electrons on the -N atom. But only p..

Boiling point of alcohols are much higher than those of alkenes, halo alkenes or ethers of comparable molecular masses. This is because in alcohols intermolecular hydrogen bonding exists due to which a large amount of energy is required to break these bo..

Due to the presence of -C N group in the molecules, they have high dipole moment and consequently possess high melting and boiling points despite lack of hydrogen bonding..

This occurs when the hydrogen bonding is between H-atom of one molecule and an atom of the electronegative element of another molecule. For example (i) hydrogen bond between the molecules of hydrogen fluoride. (ii) hydrogen ..

The boiling points of alkenes gradually increase with an increase in the molecular mass (or chain length). This indicates that inter-molecular attractions become stronger with an increase in the size of the molecule. Branched chain alkenes have lower boiling poin..

The melting and boiling points of group 14 elements are much higher as compared to those of group 13 elements. Explanation: It is because the atoms of group 14 can form four covalent bonds with each other and, therefore, there are strong binding forces between their at..
