Answered & Verified by Expert
An alkene \({ }^{\top} A^{\dagger}\) contains three \(C-C\), eight \(C-H\)-bonds, one \(\mathbf{C}-\mathbf{C} \pi\)-bond. ' \(\mathbf{A}^{\prime}\) on ozonolysis gives two moles of an aldehyde of molar mass 44 u. Write the IUPAC name of ' \(A^{\prime}\).

(i) An aldehyde with molar mass of \(44 \mathrm{u}\) is ethanal, \(\mathrm{CH}_3 \mathrm{CH}=\mathrm{O}\)
(ii) Write two moles of ethanal side by side with their oxygen atoms pointing towards each other.
(iii) Remove the oxygen atoms and join them by a double bond, the structure of alkene ' \(\mathrm{A}\) ' is
\(\underset{\text{But-2-ene}}{\mathrm{CH}_3-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}_3}\)
As required, but-2-ene has three \(\mathrm{C}-\mathrm{C}\), eight \(\mathrm{C}-\mathrm{H}\) and one \(\mathrm{C}-\mathrm{C} \pi\)-bond.
