The terminal carbon (the carbon at the end of a chain) will have three hydrogen atoms. Non-terminal alkane carbons will only have two hydrogen atoms. An alkane hydrocarbon will have the general formula CH3CH3 or C2H6 if it is a terminal alkane on both ends. Other possible formulas incl...
The results indicate two unusual effects: (1) a large negative contribution due to the destruction of orientational order in a pure n-alkane component, and (2) a positive contribution attributed to the "condensation" of a more freely-moving molecule or segment on a sterically-hindered branched ...
This reflects an arrangement of the beads in layers parallel with the confining walls, which causes an oscillation of the local density across the film. However, the alkane molecules themselves are not arranged in perfect layers. The oscillations do not vanish for long chain and/or branched ...
1D). For a simple model of an elastic spring, the so-defined resilience is nothing but the elastic constant, which directly measures the stiffness of the spring. Many research works have used this method to measure the stiffness of protein molecules31,32,33,34,35,36,37 or the average ...
effects on soil bacterial communities to some extents, and particularly shaped alkane degraders and degrading genes significantly. This study provides a better understanding on the response of alkane degraders and bacterial communities to soil alkane concentrations, which affects their biodegradation process....
An atomic force microscope (AFM) study of the structure and stability of islands of alkanethiol(C16H33SH)grown on Au(111) is presented. Ripening processes involving long-range molecular diffusion takes place at ambient temperature in the scale of days. In the partially covered surface, ripening...

It is formed by removing a hydrogen atom from an alkane chain. For examplemethaneis the simplestalkanewith a chemical formula {eq}CH_4 {/eq}. Methane is converted to a methyl group by the removal of one hydrogen as shown in the diagram, so the chemical formula becomes {eq}CH_3 {/eq...
