Identify the correct statement for the below given transformation. CH3–CH2–CH2–CH(+)–CH3 with C2H5ONa / C2H5OH gives A + B (Major / Minor).

1. A = CH3CH2CH=CHCH3, B = CH3CH2CH2CH=CH2, Saytzeff products
2. A = CH3CH2CH2CH=CH2, B = CH3CH2CH=CHCH3, Hofmann products
3. A = CH3CH2CH2CH=CH2, B = CH3CH2CH=CHCH2, Hofmann products
4. A = CH3CH2CH2CH=CH2, B = CH3CH2CH=CHCH3, Saytzeff products

Correct answer: A = CH3CH2CH2CH=CH2, B = CH3CH2CH=CHCH3, Hofmann products

Solution

The correct option identifies A and B as Hofmann products, which are typically less substituted alkenes formed under certain conditions, contrasting with Saytzeff products that are more substituted. In this case, the reaction favors the formation of the less stable alkene due to the specific reaction conditions provided.
