We provide reference notes for neb high school science, management and humanities preparation of alkanes - reference notes general method of preparation of alkanes (paraffins): alkanes can be prepared by the following methods. Alkanes preparation can be achieved within different models & mechanisms, all have their own characteristics & ways including th following a) catalytic hydrogenation of alkenes b) hydrolysis of a grignard reagent. Preparation from alkanes grignard reagents gringard reagents are very reactive and thus provide a means of organic synthesis from haloalkanes for example.
