A phosphonium ylide Wittig reagent is used in the following conversion. Draw the structure of the bromoalkane that would be used to form this phosphonium ylide by treatment with triphenylphosphine followed by butyllithium.
You do not have to consider stereochemistry.
You do not have to explicitly draw H atoms.
Do not include lone pairs in your answer. They will not be considered in the grading.
In cases where there is more than one answer, just draw one.

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.

is there any options? maybe im just not seeing them but i need the options to
