11.1 Organic Compounds — Chemistry STD 10 — Question

Organic compounds are large in number due to the following unique properties of carbon atom:
a) Tetra covalency of carbon : Carbon has four alence shell electrons. Thus it always forms covalent bonds by sharing electrons with other atoms.
b) Catenation : it is the property of combining any number of carbon atoms to form straight chains, branched chains and rings of different sizes.
c) Formation of multiple bonds: due to small size carbon atom can form multiple bonds with not only carbon but with atoms of other elements like oxyzen, nitrogen etc.
d) isomerism : It forms large number of compounds due to isomerism by means of which compounds having same molecular formula can be have different structural formula.
