Melting and boiling points
The melting and boiling point of alkaline Earth metals are characteristically low and do not show regular trends down the group. However these points are higher than the corresponding alkali metals in the same period as atoms of alkaline Earth metals have smaller size..

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..

ii) Boiling points
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 ..

>As a result of tetrahedral arrangement of H 2 O molecules in the solid state, the ice structure extends in three dimensions. Further the molecules of H 2 O are not packed closely as hydrogen bonds between oxygen and H atoms are ..
Effect of Pressure on the Boiling Point of Water
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...

The bond between two unlike atoms, which differ in their affinities for electrons is said to be a polar covalent bond. When a covalent bond is formed between two atoms of different elements, the bonding pair of electrons will lie more towards the atom, which..

Tutor Vista perceived the math apps well and I enjoyed getting to work with Tutor Vista - Savannah
Tutor offered to receive the problems in advance for preparation so that we can have highly effective sessions. Commendable. I like this very much. This is sure good service and value for the money
She should be the head of Tutor Vista. She knows how to treat her students. Her teaching style is spectacular.
The tutor really touched the right methods and formulas that would help me the most as well as a helpful practice sheet to test my knowledge of the subject. Great work!
