Q31 / 125 · BITSAT 2018 · Chemistry

The addition of HBr to 1-butene gives a mixture of products x, y and z

Figure

The mixture consists of

  • Correct answer
    A
    x and y as major and z as minor products
  • B
    y as major, x and z as minor products
  • C
    y as minor, x and z as major products
  • D
    x and y as minor and z as major products

Solution

The alkene is unsymmetrical, hence will follow Markownikoff's rule to give major product.

since, y contains, a chiral carbon, it exists in two enantiomers (x and y) which are mirror images of each other.

Figure

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