What is the difference between Alkanes, Alkenes, and Alkynes?
Question Date: 2004-05-11
Answer 1:

This is a very basic question in organic chemistry and has been well defined.The information below was taken from the following website:
organic chemistry
You can check it out and get more information.
Alkanes are hydrocarbons (compounds containing only C and H) that have single covalent bonds joining the carbon atoms. The molecular formula of all alkanes fits the expression CnH2n+2, where n is the number of carbon atoms.

Alkenes are hydrocarbons (compounds containing only C and H) that have one or more C=C double bonds (two C atoms are linked by 4 shared electrons). The general formula is CnH2n, which is two hydrogen atoms less than the corresponding alkane.

Alkynes are hydrocarbons (compounds containing only C and H) that have one or more triple bonds (two C atoms are joined by 6 shared electrons). The molecular formula fits the formula CnH2n-2 and has therefore four hydrogen atoms less than the corresponding alkane.
