Answer:
IHD = 0
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

So


IHD = 0
The index of hydrogen deficiency is zero.
Probably true because chemicals do control weed and it hurts the environment.
The answer is C
6.0m x 8.0m= 48.0m
then converting it to cm by multiply
48 x 100
