why formaldehyde cannot be prepared by hydroboration of alkynes

Asked by shreesh Kulkarni | 6th Feb, 2014, 04:39: PM

Expert Answer:

  • Alkyne has minimum two carbon atoms. Hence when oxidation takes place of an alkyne by hydroboration method to form an aldehyde, the product aldehyde should possess a carbon chain of at least two carbon atoms.
  • But formaldehyde contains only one carbon atom.
  • Hence fromaldehyde cannot be prepared by hydroboration of alkynes.
