WebA bridged ring compound is an organic compound that has two or more rings possessing a bridge. A bridge is a connection between two atoms with a single atom or a chain of atoms or even a valence bond. The two connecting atoms are … WebSep 4, 2015 · The main bridge is the bridge that includes as many of the atoms as possible that are not included in the main ring. Bridges other than the main bridge are called secondary bridges. Thus, tricyclic hydrocarbons consist of the main ring, the main bridge, and one secondary bridge.
