How many alkanes having a molecular weight of hundred, are chiral?

In organic chemistry, an alkane, or paraffin (a historical trivial name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single. Alkanes have the general chemical formula CnH2n+2. The alkanes range in complexity from the simplest case of methane (… WebbThen, small fragments of some complement proteins act as chemoattractants to recruit more phagocytes to the site of ... the stereochemical configuration at any chiral center is ... as defined above.
