Some Important Carbon Compounds – Ethanol and Ethanoic acid 1. Write the name and molecular formula of an organic compound having its name suffixed with ‘-ol’ and having two carbon atoms in its molecule. Write balanced chemical equation to indicate what happens when it is heated with excess of conc. H2S04 and the name of …
♦ Earth crust has only 0.02% carbon in the form of minerals (e.g. – carbonates, bicarbonates, coal, petroleum etc.) and atmosphere has 0.03% carbon dioxide. Inspite of its availability in such a small amount, it is highly important for our lives. ♦ Except water most of …

Carbon can exist in various physical forms in the nature with widely varying physical properties, but identical chemical properties. Such characteristic is called allotropy and the different forms are called allotropic forms or allotropes. The difference among allotropes lies in the manner in which the carbon atoms are bonded to one another. Allotropes are exclusively …
Carbon has four valence electrons. To attain noble gas configuration of the nearest noble or inert gas (He = 2 or Ne = 2,8), there are following possibilities – (1) It could gain 4 electrons and form C –4 anion. By that way, it can achieve noble gas configuration (Ne = 2,8) having 8 electrons in the …
In the Electron dot structural presentation, dots or crosses represent valence electrons which are put around an atom. Covalency of an atom is equal to the number of covalent bonds formed by the atom. Read First – Carbon and its Compounds – Introduction What is the Versatile Nature of Carbon? (a) When two atoms share one …
Why are carbon and its compounds so important or special from compounds of all the other more than hundred – odd elements of the periodic table? This is because – (a) The number of compounds that contain carbon is many time greater (due to catenation) than the number of compounds that do not contain carbon. …
