Use the following data to answer the questions below:

`DeltaH = - 116.2 " Kcal mol"^(-1)` Anthracene Calculate the resonance energy of anthracene in kcal/mol.

Text Solution

Verified by Experts

Anthracene is 14 p e's system
i.e. there are 7 p bonds
Expected (theoretical) heat of hydrogen ` = - 28.6 xx 7 = - 200.2` Kcal /mol
Observed (experimental) heat of hydrogen ` = - 116.2`
`R.E. = - 166.2 - (-200.2)`
` = 84 ` kcal/mol
