Passage -1

In addition to the standard ring systems (such as

cyclohexane), cyclic compounds can also be

bicyclic, tricyclic, etc. or they can be spirocyclic,

bicyclic or bridge head carbons. The point of

attachment of two rings are called bridge head

atoms. The formal names of bicyclic and related

ring systems are based on

(A) Total number of atoms in the molecule

(B) The number of atoms in each bridge

connecting the bridge atoms. These numbers are

written in square bracket in decreasing order

Spirocyclic compounds have two fused rings, but

only one bridge head atom. Spirocyclic

compounds are named like bicyclic compounds,

but have the prefix spirocyclo. Answer the

following questions
