Correct option is A
The correct answer is (a) H. C. Brown.
• H. C. Brown discovered that diborane reacts with aldehydes and ketones to produce dialkoxyboranes, which are hydrolyzed by water to produce alcohols.
• Herbert Charles Brown was an American chemist who won the Nobel Prize in Chemistry in 1979.
• His work on organoboranes significantly advanced the field of organic chemistry.
• The discovery of this reaction has important implications for synthetic organic chemistry.
• Dialkoxyboranes are useful intermediates in the synthesis of various organic compounds.
• The reaction discovered by Brown is known for its mild conditions and high selectivity.
• Brown’s contributions have had a lasting impact on the development of modern chemical synthesis techniques.
