Step 1

Dear student, we answer only three parts in a question. So, we are providing answers to the first three parts. If you need answers to other parts as well, kindly re-post the question, mentioning the parts you need answer for.

A) The given compound is a bicyclic compound,i.e., compound containing two cyclic rings- cyclohexyane ring and cyclopentane ring fused together. The cyclopentane ring contains 6 carbon atoms and the cyclopentane ring contains 5 carbon atoms. The common bond between the two fused rings contains no carbon atom.

For naming bicyclo compounds, the numbering of the carbon chain starts at the common atom and then oves to the chain with greater number of carbon atoms to the chain containing lower number of carbon atoms. The number of carbon atoms in the rings and the common bond are written in square brackets. The name is prefixed as "Bicyclo".

Thus, the given compound is named as: Bicyclo[4.3.0]nonane

non- used for 9 atoms in the main chain

ane - suffix used for the compound being an alkane with all saturated bonds

Step 2

B) The given compound is a substituted cyclohexane ring. The substituents attached to the ring are- cyclobutyl ring, cyclopenthyl ring and ethyl chain. The numbering of the chain is done in a way so as to give the carbon ...
