The correct answer is:
trans-pent-2-ene
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:
(It shows elimination reaction.)
Hence, trans-2-pantane is the main product and option (a) is the correct answer.
