Classification of Hydrocarbons<\/strong><\/span><\/h2>\n

The compounds containing only carbon and hydrogen in their molecules\u00a0are called hydrocarbons<\/i><\/b>.
\nHydrocarbons are classified into two categories known as open chain\u00a0<\/i>hydrocarbons <\/i>and closed chain hydrocarbons. <\/i>Open chain hydrocarbons\u00a0are also called aliphatic hydrocarbons <\/i>or acyclic hydrocarbons.<\/i><\/p>\n

Open and closed chain hydrocarbons<\/b><\/span>
\nLet us observe the following structural formulae of different\u00a0hydrocarbons.
\n1) CH3<\/sub>\u2013CH2<\/sub>\u2013CH2<\/sub>\u2013CH2<\/sub>\u2013CH3<\/sub> n-pentane, a straight chain compound.<\/p>\n

2) \"Classification\u00a0Iso pentane, a branched chain compound<\/p>\n

3) \"Classification\u00a0cyclo pentane, a cyclic compound or <\/i>a ring compound<\/p>\n

In the first example you will notice that all carbons are linked to one\u00a0<\/span>another resulting a linear structure, where as in the second example four\u00a0carbons are linked in linear way and the fifth carbon is linked to the parent\u00a0chain resulting a branch. In the third example we find that carbon chain is\u00a0closed to form a ring. So, it is a closed chain hydrocarbon or ring\u00a0hydrocarbon.<\/p>\n

All hydrocarbons (both Aliphatic and cyclic hydrocarbons) are again\u00a0classified as Alkanes, Alkenes and Alkynes:
\n1) Hydrocarbons containing only single bonds between carbon atoms are\u00a0called Alkanes<\/i>.
\n2) Hydrocarbons containing atleast one double bond between carbon\u00a0atoms are called Alkenes, <\/i>and
\n3) Hydrocarbons containing atleast one triple between carbon atoms are\u00a0called Alkynes<\/i>.<\/p>\n

Saturated and unsaturated hydrocarbons<\/b><\/span>
\nThe hydrocarbons containing only C\u2013<\/b>C single bonds are known as\u00a0saturated hydrocarbons. <\/i>All alkanes are saturated hydrocarbons. The\u00a0hydrocarbons that contain at least one double bond (C=C) or contain atleast\u00a0one triple bond (C \u2261\u00a0C) between the two carbon atoms are called\u00a0unsaturated hydrocarbons<\/i>. Alkenes and Alkynes are the examples for\u00a0unsaturated hydrocarbons.
\nStraight chain, branched chain and closed chain hydro carbon\u00a0compounds may be saturated or unsaturated. See the following examples.
