Answer:
IHD = 0
Step-by-step explanation:
Given that
C₆H₁₅N
Number of carbon atoms(n) = 6
Number of hydrogen atoms(x') = 15
Number of nitrogen atoms = 1
There is nitrogen atoms then x = x' -1
The index of hydrogen deficiency given as
![IHD=(2n+2-x)/(2)](https://img.qammunity.org/2020/formulas/chemistry/high-school/blww8jrav5fsskk8v3z2xakte4gnzxw8p0.png)
So
![IHD=(2n+2-x)/(2)](https://img.qammunity.org/2020/formulas/chemistry/high-school/blww8jrav5fsskk8v3z2xakte4gnzxw8p0.png)
![IHD=(2\time 6+2-(15-1))/(2)](https://img.qammunity.org/2020/formulas/chemistry/high-school/gndr42j8ki2gmjahpbz3fuzhfj7ji01c13.png)
IHD = 0
The index of hydrogen deficiency is zero.
