Question
Cyclopropane isomerizes exothermically to propene as shown.
The C–C single bond in propene has an estimated bond dissociation enthalpy (BDE) of 345 kJ mol-1, while the C=C double bond in propene has a BDE of 611 kJ mol-1. Assuming that the C–H bonds in propene and cyclopropane all have the same BDE, what is the estimated BDE of a C–C single bond in cyclopropane?
A.✓ Correct
308 kJ mol-1
B.
329 kJ mol-1
C.
423 kJ mol-1
D.
924 kJ mol-1
