Molecular formula : CH 4 Electronic formula : Shape of the methane molecule: Tetrahedral Bond angle: 109.5 o ..

Water of Crystallisation : When crystals of certain salts are formed, they do so with a definite number of molecules of water, chemically combined in a definite proportion. Water of crystallisation is the number of water molecules, chemically combined in a definite molec..

a) Water of Crystallisation - When crystals of certain salts are formed, they do so with a definite number of molecules of water, chemically combined in a definite proportion. Water of crystallisation is the number of water molecules, chemically combined in a definite molecular ..

The melting and boiling points of covalent compounds are generally low. This is because of the fact that the forces between the molecules are weak and thus are easily overcome at low temperature..

Dienes are unsaturated hydrocarbons containing two carbon-carbon double bonds per molecule. Their general formula is C n H 2n-2 . Dienes and alkynes are functional isomer..

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 soft solids. As the..

Alkanes are saturated hydrocarbons having only single bonds between the carbon atoms of their molecules. The general formula of alkanes is C n H 2 n + 2 . Alkanes are called paraffins because of their low reactivity (in Latin paraffin means- less reactivity..

In 1923, J.N.Bronsted and T.M.Lowry proposed a more general theory known as the Bronsted-Lowry proton transfer theory. According to this concept, any hydrogen containing species (a molecule, a cation or an anion), which is capable of donating one or more protons to any oth..

Carbohydrates - Introduction - Carbohydrates are the organic molecules that are composed of elements carbon, hydrogen and oxygen. These carbohydrates are referred to as saccharides. Carbohydrates are defined as polyhydroxy-aldehydes or polyhydroxy ketones or compounds, which produce them ..

The general formula of Haloalkane (CnH 2 n + 1 - X) or Haloarene is 'RX' where R - is an alkyl or aryl group and X is a halogen atom (F, Cl, Br or I). The halogen derived hydrocarbons are a highly reactive class of compounds. The reactivity is due to the presence of polar carbon..
