Question number 51.
The iupac name of the compound
With the steps of why it is named so
Answers
Identify total number of carbon atoms in the molecule. It is six in the given case, so it'll be a hexane. Hence option A is wrong.
Start numbering from one of the bridgehead and take longest path to next bridgehead. That will be how you will be numbering it. After that, continue numbering along next longest path until all carbon atoms are numbered.
Identify number of carbon atoms in each path. Do not consider bridgehead while doing this counting.
The first longest path consist of 2 carbon atoms.
The second longest path also consist of 2 carbon atoms.
The third path has no carbon atoms (Do not consider bridgehead carbon atoms).
The compound starts with 'bicyclo' since it has two fused rings.
The number of carbon atoms in each path is written in brackets
Finally, the total number of C-atoms in the molecule is written.
The answer to this question, following above steps, will be
Bicyclo [2.2.0] hexane
That is, option D will be the right answer.
