What is cycloalkane and cycloalkene respectively ?

Interpret the order in terms of the structure of each molecule and comment particularly on the different results in this pair :
cyclohexane and cyclohexene .

please help me !! Thanks a lot!!!

Right mate, the main difference between the two molecules is a double bond.
Cycloalkane has no double bonds where as CycloalkEnes do.

That help at all?

okay . i see the differnence .
but :
actually what are cyclohexane and cyclohexene used for ?
also , what are the polarity of them respectively ? Is the polarity related to the double bond ?
Thx!

here are some of the industrial uses of cyclohexane

Electroplating - Vapor Degreasing Solvents
Solvents - Rubber Manufacture
Varnish Solvents
also used as a solvent to dissolve resins, fats, waxes, oils, bitumen

cyclohxene uses-
Used in organic synthesis and as a solvent for oil extraction and catalysts
Preservative for cosmetics industry.
used in oil based paints
and in fungicides


as for the polarity i would guess that because of the double bond it would make the molecule slightly polar because there is not another Hydrogen ( on the other side) to cancel out the charges.


hope this helps with my limited knowledge of chemistry!!!

lol I'm glad u put this post on Tak now i've found a quick link to remind myself bout cycloalkanes/enes, i always get their uses the wrong way around
