What are \(Y\) and \(Z\) in the following reaction sequence?

• A

  \(\mathrm{Y} - \mathrm{NaOH} / \mathrm{CaO}; \mathrm{Z} - \mathrm{CH}_3\left(\mathrm{CH}_2\right)_2 \mathrm{CH}_3\)
• B

  \(\mathrm{Y} - \mathrm{NaOH} / \text { electrolysis }; \mathrm{Z} - \mathrm{H}_3 \mathrm{C}-\mathrm{CH}_3\)
• C

  \(\mathrm{Y} - \mathrm{NaOH} / \mathrm{CaO}; \mathrm{Z} - \mathrm{H}_3 \mathrm{C}-\mathrm{CH}_3\)
• Correct answer
  D

  \(\mathrm{Y} - \mathrm{NaOH} \text { /electrolysis }; \mathrm{Z} - \mathrm{CH}_3\left(\mathrm{CH}_2\right)_2 \mathrm{CH}_3\)

Solution

Thus, option (4) is correct.

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