Based on the following reaction identify alkene A O ₃ / ( H ₂ O ) / Zn 2 HCHO + CHO CHO

Options

  1. ACH ₂= CH - CH = CH ₂
  2. BCH ₃- CH = CH - CH ₃
  3. CCH ₃- CH ₂- CH = CH ₂

Correct answer

B. CH ₃- CH = CH - CH ₃

Step-by-step solution

Alkene A is CH ₂= CH - CH = CH ₂ CH ₂= CH - CH = CH ₂+ O ₃
