Compounds. Lecture six:. عضوية . Alkaloids and Heterocyclic Compounds. Alkaloids :-. Alkaloids are a group of naturally occurring chemical compounds that mostly contain nitrogen atom in the heterocycles and originate from amino acids. This group also includes some related compounds with neutral, and even weakly acidic properties. . Bond Fission. Alkanes are not particularly reactive due to the non-polar nature of their bonds.. They can, however, react with halogens in the presence of sunlight or UV light where halogenoalkanes are produced along with steamy fumes of the corresponding hydrogen halide.. Lecture . Four:. عضوية . Alcohols. Alcohols are some of the most important molecules in organic chemistry. They contain the hydroxyl functional group (-OH), bonded to a carbon atom of an alkyl, or substituted alkyl group.
