Devise the most efficient synthesis for the carboxylic acid below using a starting material and reagents from the tables. give your route by specifying the number of the starting material followed by the letters of the reagents you would use beginning with the first step. the answer 4fh means treat t-butanol(4) with conc. hcl(f) then treat the product with koh in alcohol(h). starting materials reagents the most efficient synthetic route is .

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.
