Assertion : $2-$ Bromobutane on reaction with sodium ethoxide in ethanol gives $1-$ butene as a major product.
→Reason : $1-$ Butene is more stable than $2-$ butene According to Saytzeff's rule, $2-$ butene should be the product which is more branched or substituted compound and hence, more stable than butene $-1$
