The reaction of an alkene X with bromine produce a compound Y , which has 22.22 % C, 3.71 % H and 74.07 % Br. The ozonolysis of alkene X gives only one product. The alkene X is : [Given: atomic mass of c=12 ; H=1 ; B r=80]

Options

  1. Aethylene
  2. B1 -butene
  3. C2 -butene
  4. D3-hexene

Correct answer

C. 2 -butene

Step-by-step solution

From the data given, X will be CH ₃- CH = CH - Ch ₃ which on ozonolysis gives ethanal.
