Oh okay, so in benzene the carbon to carbon bonds are all the same length, and that length is in between the length of C-C and C=C bonds?.. 0.139 according to the book..
What about the Kekule model, what does that say about the bond lengths, and what about C-C and C=C bond lengths in general?
(Original post by Kasam) Can someone explain the part about carbon-carbon bond lengths in:
And also can you explain the actual lengths of C-C and C=C bonds in regular compounds, like alkanes/alkenes.
The book is a little on this part, for me atleast.
Thanks a bunch!
The carbon carbon bond lengths in Kekule's model are in between the lengths of an alkane and and alkene's bond length. This is unusual because Kekule suggested that there are 3 double bonds and 3 single bonds, therefore you would EXPECT there to be 3 bonds the same size and the other 3 bonds the same size but this isn't the case as all 6 c-c bonds in benzene are in between the length of an alkane and alkene's bond length.
