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.

1. If life arose by “chemical evolution” (which is supposed to be new chemical compounds arising by random chance), what should be the proportion of each of the L- and D-enantiomers present in chiral compounds produced by random chance? How does this match with what we see in living systems? What conclusion can you make from this about the likelihood of life arising by “chemical evolution?" 2. Why does chirality make a difference when new medications are developed? What is an ethical way of addressing this concern in the development process?
