Elimination reaction of 2-Bromo -pentane to form pent-2-ene is
(1)`beta`- Elimination reaction
(2) Follows Zaitsev rule
(3) Dehydrohalogenation reaction with `OH^(-)` ?

Answer

D

Explanation

`CH_3-underset("(Reactant)")underset(Br)underset(|)(CH)-CH_2-CH_3-CH_3 overset("Elimination")(rarr)`
`CH_3-CH = CH-CH_2-CH_3`

(1) The process is known as `beta`- elimination as it involves elimination of `beta`- Hydrogen .
(2) Pent-2-ene is major product known as Saytzeff.s Product and it is more stable alkene. Since more substituted alkene is formed , it follows zaitsev.s rule.
(3) Since `.H.` and `.Br.` are removed. It is dehydrobalogenation .
Thus statements 1,2,and 3 are correct.
