Molecule structure formula of cyclopropane

Cyclopropane is a cycloalkane molecule with the molecular formula C3H6 consisting of three carbon atoms linked to each other to form a ring, with each carbon atom bearing two hydrogen atoms. The bonds between the carbon atoms are a great deal weaker than in a typical carbon-carbon bond. This is the result of the 60 angle between the carbon atoms, which is far less than the normal angle of 109. This ring strain has to be subtracted from the normal C-C bond energy, making the resultant compound more reactive than acyclic alkanes and other cycloalkanes such as cyclohexane and cyclopentane.

Boiling point: -32.8C Freezing point: -127C

The naturally ocurring pyrethrum insecticides (found in certain Chrysanthemum species) contain a cyclopropane ring.de:Cyclopropan
