Q16 / 90 · JEE Main 2022 (28 Jul Shift 1) · Chemistry

Identify the correct statement for the below given transformation.

Figure

  • A

    A-CH3CH2CH=CH-CH3,

    B-CH3CH2CH2CH=CH2, Saytzeff products

  • B

    A-CH3CH2CH=CH-CH3,

    B-CH3CH2CH2CH=CH2,
    Hafmann products

  • Correct answer
    C

    A-CH3CH2CH2CH=CH2,

    B-CH3CH2CH=CHCH3,
    Hofmann products

  • D

    A-CH3CH2CH2CH=CH2,

    B-CH3CH2CH=CHCH3,
    Saytzeff products

Solution

The Hofmann rule states that the major alkene product is the least substituted and least stable product when it comes to asymmetrical amines.

Figure

So, major product will be pent-1-ene and minor product will be pent-2-ene.

Hence, the correct answer is option: 'C'.
