In open kinetic chain exercises, the segment furthest away from the body — known as the distal aspect, usually the hand or foot — is free and not fixed to an object. In a closed chain exercise, it is fixed, or stationary.
What are open chain and closed chain compounds?
In open chain hydrocarbons, carbon atoms are linked to form a continuous straight or branched chain. In closed chain hydrocarbons, carbon atoms are linked to form a ring structure. 2. They are not aromatic compounds.
What are closed chain compounds?
An arrangement of atoms of the same type that forms a ring. Benzene and naphthalene are closed-chain compounds.
What are the open chain compounds?
The open chain or acyclic compounds are those in which carbon atoms are linked to each other either in linear or branched fashion such that the molecule is having open chain structure. These compounds are also called aliphatic compounds (Greek word : aliphar meaning fat).
