Need to know the number of C-C-C bonds in petane C5H12?

Need to know the number of C-C-C bonds in petane C5H12?


Gronert of UCSF reports bond energies for C-H, C-H-C, etc.


Need to know the number of C-C-C bonds that exist in pentane. Know there are 5 carbon bonds in the formula, 12 C-H bonds, but need the C-C-C bonds.


Thanks, Greg in Alaska

thanks for the answers. Need to know how many "C-C-C" carbon bonds there are in Pentane, how is this calculated.


I know pentane has 5C bonds, 4 C-C bonds, but how many "C-C-C" bonds.


Thanks much!!

3 c-c-c bonds:





carbons 1,2,3


carbons 2,3,4


carbons 3,4,5
Reply:As a general rule, anything with an "ane" in it's name is a saturated aliphatic hydrocarbon, unless it says something like "iso-" or has numbers in front of it. This means that it is a single straight chain, without any double bonds. Therefore the carbons in pentane, C5H12, are H3C-CH2-CH2-CH2-CH3, or 3 carbon-carbon-carbon bonds.
