Answer 1

This spiro compound has ten carbon atoms and hence, parent compound is named as spirodecane. But, the numbers given in the square bracket in this question are incorrect. Because the lower number is written first and then the greater number. Hence, the correct IUPAC name of this compound is spiro[4.5]decane.

Therefore, the correct answer is 0.
