Answer :
Answer:
d.) Butyl cyclohexyl ether
Explanation:
The Williamson synthesis is an organic reaction that produces an ether. The reactants are a primary haloalkane and a deprotonated alcohol (or alkoxide):
ROH + R'X → ROR'
Where R and R' are any carbon chain, and X is a halogen (Cl,Br or I).
In this case R = cyclohexyl and R' = butyl.
