2-bromopentane is heated with potassium ethoxide in ethanol. The major product is
- A trans-pent-2-ene
- B 2-ethoxypentane
- C pent-1-ene
- D 3-ethoxypentane
Answer & Solution
Correct Answer
(A) trans-pent-2-ene
Step-by-step Solution
Detailed explanation
When 2-bromopentane is heated with potassium ethoxide, we get trans-pent-2-ene. Because when alkyl halides react in ethanol with potassium ethoxide, it give trans product as major product due to more symmetrical nature as compared to cis-isomer. The reaction occurs as follows:…
