Vedclass · Answer

(C) The reaction of $2$-bromopentane with ethanolic potassium ethoxide is a dehydrohalogenation reaction (an $E2$ elimination reaction). According to Zaitsev's rule,the more substituted alkene is the major product. $2$-bromopentane $(CH_3-CH(Br)-CH_2-CH_2-CH_3)$ undergoes elimination to form two possible alkenes: $1$-pentene and $2$-pentene. $2$-pentene is more substituted than $1$-pentene and is therefore the major product. Among the isomers of $2$-pentene,the trans-isomer is more stable than the cis-isomer due to less steric hindrance. Thus,trans-$2$-pentene is the major product.

What is the major product formed when $2$-bromopentane is heated with ethanolic potassium ethoxide $(C_2H_5OK)$?
