Dear Student,
Please find below the solutions of your asked queries:
89. The Structure of tertiary butyl group is given below-
So, the IUPAC name of tertiary butyl group becomes 2-Methylpropyl.
Therefore, option (a) is correct.
90. The IUPAC name of the compound given above is 1-Cyclopropylethanol.
As, the ethane chain contains the functional group, therefore, it will be considered as a main chain and cyclo propane ring will be considered as substituent.
Therefore, option (d) is correct.
Hope this information clears your doubts about the topic.
Keep asking!!
