Imagine that a chemist has cyclohexanone, triphenylphosphine, butyllithium, and 2-bromobutane. Draw the organic product resulting from using these chemicals in the Wittig reaction.

Reaction product shown in the image attached.

Explanation:

The Wittig reaction also known as Wittig olefination is a reaction in organic chemistry

Involving an aldehyde or ketone (CO or CHO groups) with a triphenyl phosphonium ylide (also called a Wittig reagent ) to give an alkene and triphenylphosphine oxide .

Hence the organic reaction between a carbonyl and a phosphonium ylide is known as a Wittig reaction. The phosphonium ylide used in this reaction is obtained by reaction of 2-bromobutane and phosphine oxide followed by butyl lithium.

The carbonyl now reacts with the phosphonium ylide produced in the first step to yield the final product.

The sequence of the reaction is shown in the image attached.

if you mean hydrogen and oxygen then water is the product
