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.

Long-range coupling between protons more than two carbon atoms apart is sometimes observed when bonds intervene. An example is found in 1-methoxy-l-buten-3-yne. Not only does the acetylenic proton, Î—a, couple with the vinylic proton Hb, it also couples with the vinylic proton Hc, four carbon atoms away. The data are: Construct tree diagrams that account for the observed splitting patterns of Î—a, Hb, and Hc.

The diasteromers of 4-t-butylcyclohexanol that you make can be distinguished by the splitting patterns of the proton attached to the carbon bearing th OH group. This is due to the fact that the H that is axial is a triplet of triplets because it is coupled to to sets of non-eqivalent protons, while the equatorial H is coupled to 4 equivalent hydrogens and is a pentet.
