Step 1

The structure of cyclopropane is

Step 2

There are three CH2 groups in the molecule of cyclopropane. Molar heat of combustion per CH2 group is help_outlineImage TranscriptioncloseAH for cyclopropane = -2089kJ/mol there are 3 CH, groups therefore -2089kJ AH per CH, group of cyclopropane= 3mol = -696.3kJ/mol fullscreen
Step 3

The structure of cyc...
