TS EAMCET 9-Sep-2020 Shift 2 Solved Paper

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− pentane is the main product and option (a) is the correct answer.
