Vedclass · Answer

(D) The reaction of $2-$bromopentane with sodium ethoxide $(NaOCH_2CH_3)$ in ethanol is a dehydrohalogenation reaction (an $E2$ elimination reaction). Since $2-$bromopentane is an unsymmetrical secondary alkyl halide,it undergoes elimination to form alkenes. The major product is the more stable alkene,which is $2-$pentene. $2-$pentene exists as two geometric isomers: $trans-2-$pentene and $cis-2-$pentene. $trans-2-$pentene is more stable than $cis-2-$pentene due to less steric hindrance. Therefore,both $trans-2-$pentene and $cis-2-$pentene are formed as products.
