Question: The choices are Angle Strain, Torsional Strain, and Steric Strain for each of the three boxes in that order. Q6- For each of the following molecule circle the one that is more stable. Justify your answer by marking an X next to all the different kinds of strain present in the unstable molecule. When comparing two different cyclic hydrocarbons consider the optimize conformation of the molecule for example chair conformation for cyclohexane etc. Only when it states "planar" underneath the molecule compare the planar structure.

Alkanes and Cycloalkanes

Alkanes are saturated organic compounds which are made up of C and H atoms. Alkanes have the general formula of CnH2n+2. Alkane contains sp3 hybridized carbon atoms with four sigmas (σ) bonds & every hydrogen atom is connected with one of the carbon atoms. The size of the alkane could be determined by the number of carbon atoms located in it.
