Which of the following compounds is a heterocyclic aliphatic amine? The halogen derivatives of alkanes are called haloalkanes. The general term aliphatic hydrocarbon refers to a compound that has a structure based on straight or branched chains or rings of carbon atoms. 2. Aliphatic compounds are also known as non-aromatic compounds. Aromatic compounds having Benzene rings this is a typical chemical structure that contains six Carbon atoms, cyclically bonded with alternating double bonds.whereas the aliphatic does not have benzene rings. These are the compounds which have just carbon and hydrogen elements in them. The similarity is that they are both hydrocarbons, aliphatic compounds are hydrogen and carbon. When two or more substituents are present, give each substituent a number corresponding to its location on the longest chain. Such a compound is said to be nonaromatic (or aliphatic). A straight chain aliphatic hydrocarbon with 35 C atoms ? 61.1 - Hydrocarbons more complex then those envisioned in Rule A-12, composed of cyclic nuclei and aliphatic chains, are named according to one of the methods given below.Choice is made so as to provide the name which is the simplest permissible or the most appropriate for the chemical intent.
