Rank the following groups in order of decreasing priority: A. bondCtbondCH B. bondCH(CH3)2 C. bondCH2CH3 D. bondCHdbondCH2

Answer:

(CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3

Explanation:

Giving the following ; CH3, CH2CH3, CH2CH2CH3, (CH2)3CH3

Priority increases as the number of CH2 group increases and vice versa, as such the one with more CH2 group will be the highest priority and the least compound with the small CH2 group attached, will have the smallest priority.

The arrangement is as follows ; (CH2)3CH3 > CH2CH2CH3 > CH2CH3 > CH3

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

Len [333]

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:
