A) 1.51 kJ
B) 15.1 kJ
C) 151 kJ
D) 1511 kJ
Correct Answer: C
Solution :
Experimental heat of atomisation of benzene\[=5535\text{ }kJ\text{ }mo{{l}^{-1}}\]. Theoretical heat of atomisation (breaking of\[3C-C\]bonds, \[3C=C\]bonds and\[6C-H\]bonds) is \[3\times 347.3+3\times 615.0+6\times 416.2=5384.1\] Hence, resonance energy of benzene \[=5535-5384.1=151\text{ }kJ\]You need to login to perform this action.
