The hydrogen deficiency index( HDI) of strigol is = 10
<h3>How to calculate HDI:</h3>
The hydrogen deficiency index is used to measure the number of degree of unsaturation of an organic compound.
Strigol is an example of an organic compound because it contains carbons and hydrogen.
To calculate the HDI using the molecular formula given (C19H20O6) the formula for HDI is used which is:
![hdi = \frac{1}{2} (2c + 2 + n - h - x)](https://tex.z-dn.net/?f=hdi%20%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%282c%20%2B%202%20%2B%20n%20-%20h%20-%20x%29)
where C = number of carbon atoms = 19
n= number of nitrogen atoms = 0
h= number of hydrogen atoms = 20
X = number of halogen atoms = 0
Note that oxygen was not considered because it forms two bonds and has no impact.
There for HDI =
![\frac{1}{2} (2 \times 19 + 2 + 0 - 20 - 0)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%282%20%5Ctimes%2019%20%2B%202%20%2B%200%20-%2020%20-%200%29)
HDI=
![\frac{1}{2} (40 - 20)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2840%20-%2020%29)
HDI =
![\frac{1}{2} \times 20](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20%5Ctimes%2020)
HDI = 10
Therefore, the hydrogen deficiency index of strigol is = 10

Answer: Mass Of CFC that needs to evaporate for the freezing of water = 328.24 g
Explanation: Heat gained by the CFC = Heat lost by water
Heat lost by water = Heat required to take water's temperature to 0°c + Heat required to freeze water at 0°c
Heat required to take water's temperature from 33°c to 0°c = mCΔT
m = 201g, C = 4.18 J/(gK), ΔT = 33
mCΔT = 201 × 4.18 × 33 = 27725.94 J
Heat required to freeze water at 0°c = mL
m = 201g, L = 334 J/g
mL = 201 × 334 = 67134 J
Heat gained by CFC to vaporize = mH = 27725.94 + 67134 = 94859.94 J
H = 289 J/g, m = ?
m × 289 = 94859.9
m = 328.24 g
