what are the difference between open chain compounds and closed chain compounds
Answers
Answer:
Acyclic or Open Chain Compounds:
These compounds are also known as aliphatic compounds, they have branched or straight chains. Following are the examples in this category.
Acyclic
Examples of Acyclic or open chain compounds
2. Alicyclic or Closed Chain or Ring Compounds:
These are cyclic compounds which contain carbon atoms connected to each other in a ring (homocyclic). When atoms other than carbon are also present then it is called as heterocyclic. Examples of this type are as follows:
Alicyclic

They exhibit some properties similar to aliphatic compounds.
3. Aromatic Compounds
They are a special type of compounds which contain benzene and other ring related compounds. Similar to alicyclic, they can also have heteroatoms in the ring. Such compounds are called heterocyclic aromatic compounds. Some of the examples are as follows:
(a) Benzenoid aromatic compounds
Aromatic

(b) Non-benzenoid aromatic compounds

4. Heterocyclic Aromatic Compounds

Organic compounds can also be classified on the basis of functional groups into families or homologous series.
Cyclic compounds are called closed chain or ring compounds e.g.. cyclohhexane (CH2), cyclopentane (CH cyclobutane (C,Hg), cyclopropane (C₂H₁) etc.
