Alkanes contain only C-C and C-H s bonds. Dr. Michael Findlater.

University. Alkanes are aliphatic hydrocarbons. Organic Chemistry I (CHEM 3305 ) Academic year

The most stable conformation of cyclohexane is the chair form shown to the right. The heat of combustion per methylene group was determined experimentally for cycloalkanes of different ring sizes and this data was compared with that of n-alkane. Angle strain is the increase in potential energy of a molecule due to bond angles deviating from the ideal values. Each carbon atom in the cyclopropane ring is tetracordinate. The stability of the cycloalkanes can be explained using thermochemistry.
Here, the electron clouds of the Cl atoms are close together, and they repel each other.

Course. Texas Tech University. ANGLE STRAIN arises when the C-C-C bonds of the ring depart (because of geometric necessity) from the ideal tetrahedral angle preferred for sp3 carbon. Cyclopropane.
Organic Chemistry 5th Edition by Smith – Test Bank sample Questions Which of the following statements about alkanes is not true? Consider a non-cyclic molecule such as 1,3-dichloropropane.

The total ring strain in cyclopropane is 114 kJ mole − 1. First, it should be pointed out that cyclohexane (6-carbons) is more stable than rings with more than 6 carbons and less than 6 carbons. But there is free rotation about the C-C σ bonds.

eg: Cyclopropane Due to the rigidity of the cyclopropane ring it could assume only one conformation, namely the planar conformation. Cyclopropane has only three carbon atoms, so it is a planar molecule. The C-C-C bonds are very close to 109.5 o, so it is almost free of angle strain.It is also a fully staggered conformation and so is free of torsional strain. It is strained because the “bent” carbon–carbon bonds overlap poorly. Alkanes are acyclic or cyclic. The ideal bond angle at a tetracordinate carbon atom is 109.5º. Acyclic alkanes have two fewer H atoms than cyclic alkanes with the same number of carbons. Again, in chair cyclohexane this angle just happens to be virtually identical to the tetrahedral angle, so that neither angle nor torsional strain occurs in cyclohexane in the chair form.
