1,3,5 CycloHexaTriene
« on: February 27, 2009, 12:48:45 AM »
Hello everyone.
I'm doing some modeling with ArgusLab.
I modeled out Benzene and saw that its heat of formation was about 21 kcal/mol and the Heat of formation for 1,3,5 CycloHexaTriene is 32 kcal/mol
Can anyone confirm this?

Also, using ArgusLab, I was trying to do the Electrostatic Potential however the maps for both of the molecules look exactly the same. From what I understand, benzene's pi electrons should be delocalized whereas cyclohexane's shouldn't. In this case, the ESP Maps for both should be different.

Can anyone help out? Any help will be greatly appreciated

Heats of hydrogenation for benzene-49.8Kcal/mole
and calculated value for heats of hydrogenation of cyclohexatriene is expected to be very high-85.8Kcal
1,3,5 -cyclohexatriene is nothing but benzene only.It has pi electron clouds which are delocalized due to this Heats of hydrogenation -49.8Kcal/mole
