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

(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

hi my dude or dudette

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
