the questions of effects hydrogen bond of boiling point

All the hydrides are volatile. The volatility increases from H 2 O to H 2 S and then decreases. This is clear from their boiling points as given below:..

1. Pure H 2 SO 4 is colorless but commercial acid is yellow in color due to presence of impurities. 2. Highly concentrated H 2 SO 4 (98%) has a specific gravity of 1.84 and high boiling point of 621K. The high boiling..

Pure water is transparent, tasteless, colourless and odourless. It readily picks up the flavour of any substance dissolved in it. Water in thick layers appears greenish blue. Due to the presence of intermolecular hydrogen bonding in H 2 O molecules, the ..

Water is the most common substance on the earth's surface. Water has interesting structure and this accounts for its many unusual properties. One of the most important of these is its ability to dissolve a variety of compounds. It dissolves ionic compounds, many polar inorganic and organic compoun..

In diamond, the carbon atoms are arranged tetrahedrally (sp 3 hybridisation of C): each C atom is linked to its neighbors by four single covalent bonds. This leads to a three-dimensional network of covalent bonds...

Characteristics of Covalent Compounds - 1) Covalent compounds consist of molecules and not ions. The molecules do not have any electric charge on them. The molecules are held together by weak forces called Van der Waal's forces . 2) Covalent compounds are either gases, volatile liquids or..

Molecular hydrides are soft. They are generally, volatile in nature and have low melting and boiling points. They have low electrical conductivity. The electronegativity difference between hydrogen and the atom bonded to it, determines the properti..

Homologous Series - All organic compounds are made up of a progressively building chain of carbon atoms with a number of compounds having the same functional groups. Such a series of similarly constituted compounds are called a homologous series. Members of a homologous group are similar in structu..

The chief source of free nitrogen is atmospheric air and nitrogen is usually prepared from it. Air free from dust, water vapour and carbon dioxide is compressed in a compression chamber for liquefaction. Firstly, the pressure on the air is increased to about 200 atmospheres. It is then released thr..

The structure of a nitro group can be represented as a resonance hybrid of two equivalent zwitter ionic polar structure..
