Strigol is an important plant hormone that is released by crops such as rice and sugarcane. Unfortunately for these plants, stri

gol also activates the germination of any nearby witchweed seeds, resulting in the destruction of the crops by the parasitic weed. Strigol has nineteen carbon atoms. Determine the HDI of strigol, as well as its molecular formula. Strigol has four rings and five double bonds, for a total hydrogen deficiency index of 10 . If saturated, a compound with 19 carbon atoms would have 40 hydrogen atoms, but an HDI of 10 means that 20 hydrogen atoms are missing. So there must be 20 hydrogen atoms in the formula. Inspection of the structure also reveals 6 oxygen atoms, so the molecular formula of strigol must be C 19 H 20 O 6 .

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)

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)

HDI=

\frac{1}{2} (40 - 20)

HDI =

\frac{1}{2}  \times 20

HDI = 10

Therefore, the hydrogen deficiency index of strigol is = 10

What is the difference between an anion and a cation
Svetlanka [38]

Cations and anions are both ions. The difference between a cation and an anion is the net electrical charge of the ion. Ions are atoms or molecules which have gained or lost one or more valencee electron giving the ion a net positive or negative charge. Cations are ions with a net positive charge.
