Question

Which of the following is correct statement?

Statement A: When the ring contains more or equal number of carbon atoms than the alkyl group attached to it, then it is named as a derivative of cyclo alkane and the alkyl group is treated as substituent.

Statement B: When the alkane chain contains greater number of carbon atoms than the carbon atoms present in the ring, the compound is considered as the derivative of alkane and the ring is designated as substituent.

Statement C: Word cyclo is prefixed before the name of alkene and alkyne having the same number of carbon atoms as in the ring.

• A. All the statement are correct
• B. All the statements are incorrect
• C. A, B are correct and C is incorrect
• D. A, B are incorrect and C is correct

Answer 1

The correct option is A All the statement are correct

All the statements are correct.

All are according to IUPAC rules.

If ring has more carbon atoms that chain is considered as substituent .

If chain has more 'C' atoms, ring is considered as substituent .

For our better understanding , we have to write the word 'cyclo' before the name for ring structures.
