Question

Which of the aldehyde is most reactive ?

  1. C subscript 6 end subscript H subscript 5 end subscript minus C H O    
  2. C H subscript 3 end subscript C H O    
  3. H C H O    
  4. All the equally reactive    

The correct answer is: H C H O


    Among Carbonyl Compounds, reactivity decrease with increase in alkyl groups as alkyl groups (+I effect) decrease positive character on C-atom. Thus, the correct order of reactivity is
    H C H O greater than C H subscript 3 end subscript C H O greater than C subscript 6 end subscript H subscript 5 end subscript C H O
