Question

Saytzeff's rule predicts that in an elimination reaction, the substituted product will be the most stable.

• A. most
• B. least
• C. less

Answer 1

The correct option is A most

Saytzeff rule states that in dehydrohalogenation reactions, the preferred product is that alkene which has the greater number of alkyl groups attached to the doubly bonded carbon atoms.
For example:
Dehydrohalogenation of 2-bromobutane yields two products 1-butene -and 2-butene -
Out of these 2-butene is the major product (80%) as it is more substituted and thus, more stable.
