Chemistry feels lonely without Organic!

Chemistry Level 4

An alcohol

  • has 4 carbon and 1 oxygen atoms
  • gives white/colourless in Victor Mayer test.

Here are the sequential reactions carried out on it.

Reactions:

  • Add Cu to it and heat it to 350°C.
  • Then add \( \ce{B2H6} / \ce{H2O2} / OH^- \).
  • Add PCC to it.
  • Then add isopropyl Magnesium Chloride to it followed by \( H^+ \)
  • Add \( {P}_{4} + {Br}_{2}\) to it.
  • Now add \( \ce{Br2} ( 1 equivalent ) , h\nu \)
  • Now add \( \ce{NaNH2} (1 equivalent) \) . Consider the stable (major ) product.
  • Add Hypobromous acid to it.
  • Now add aq. KOH (excess ) to it.
  • Now add Methyl Magnesium Iodide to it in the presence of \(H^+ \).
  • At last add \( H^+ \) to it.

Enter your answer as the Molecular weight of the end product.

Hints and Details

  • Every step of reaction will happen.
  • Consider the major products,
  • End product has a ketonic group.
