The major product formed in dehydrohalogenation reaction of 2-Bromo pentane is Pent-2-ene. This product formation is based on?

According to Saytzeff’s rule, in Dehydro halogenation reactions, the preferred product is that alkene which has the greater number of alkyl groups attached to the double bonded carbon atoms.

(1) Huckel’s rule:
It is used to determine aromatic compounds.
Huckel’s rule is $(4n+2)\text{пе-}$
where
n = 0,1,2, ..........
(3) Hund’s rule:
When degenerate orbitals are available, pairing occurs only after each of the degenerate orbital is singly occupied.
(4) Hoffmann rule:
During elimination reaction of
(a) cope elimination
$\text{(b)}{\mathrm{E}}_{\mathrm{ICB}}\text{reaction}$
least stable and least substituted alkene is formed as major product.
