One mole of a symmetrical alkene on ozonolysis gives two moles of an aldehyde having a molecular mass of 44u44 \mathrm{u}. The alkene is

Options

  1. Apropene
  2. B1-butene
  3. C2-butene
  4. Dethene

Correct answer

C. 2-butene

Step-by-step solution

2-butene is symmetrical alkene CH3−\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}−CH3O3Zn/H2O2⋅2⋅CH3CHO-\mathrm{CH}_3 \frac{\mathrm{O}_3}{\mathrm{Zn} / \mathrm{H}_2 \mathrm{O}} 2 \cdot 2 \cdot \mathrm{CH}_3 \mathrm{CHO} Molar mass of CH3CHO\mathrm{CH}_3 \mathrm{CHO} is 44u44 \mathrm{u}.
