Question

Which one of the following has an optical isomer?

  1. left square bracket Z n invisible function application left parenthesis e n right parenthesis subscript 2 end subscript right square bracket to the power of 2 plus end exponent    
  2. open square brackets Z n left parenthesis e n right parenthesis open parentheses N H subscript 3 close parentheses subscript 2 right square bracket blank to the power of 2 plus end exponent close    
  3. open square brackets C o left parenthesis e n right parenthesis subscript 3 end subscript close square brackets to the power of 3 plus end exponent    
  4. open square brackets C o open parentheses H subscript 2 end subscript O close parentheses subscript 4 end subscript left parenthesis e n right parenthesis close square brackets to the power of 3 plus end exponent    

The correct answer is: open square brackets C o left parenthesis e n right parenthesis subscript 3 end subscript close square brackets to the power of 3 plus end exponent
