Question

distinguish Open chain hydrocarbons -closed chain hydrocarbons
Alkene​

Answer 1

Answer:

(1) open-chain hydrocarbons (hydrocarbon molecules of carbon atoms in the open-chain binding) saturated hydrocarbons (alkanes), unsaturated hydrocarbons [olefins and polyenes (including carbon-carbon double bond, unstable), alkynes and polyalkenes (Carbon-containing carbon triple bond, more unstable)]

(2) Alicyclic hydrocarbons [cycloalkanes (cyclopropane), cycloalkenes, cycloalkynes]

(3) Aromatic hydrocarbons [monocyclic aromatic hydrocarbons (benzene and its homologues), fused ring aromatic hydrocarbons (naphthalene, anthracene and other fused ring aromatic hydrocarbons and their homologues), polycyclic aromatic hydrocarbons (polycyclic aromatic hydrocarbons and their homologues)].
