Question

Carbene intennediates are produced by the photo lysis of diazomethane open parentheses C H subscript 2 end subscript N subscript 2 end subscript close parentheses or ketene open parentheses C H subscript 2 end subscript equals C equals 0 close parentheses. They are also produced by the reaction of C H X subscript 3 end subscript with base or by Simmons-Smith reaction. There are two types of carbenes, singlet and triplet. They are so called due to their spin state.
Which carbene is produced in the following reactions

  1. CCIBr    
  2. CBrI    
  3. CCII    
  4. All    

The correct answer is: All
