Question

PhCHO + MeCHO Error converting from MathML to accessible text.

  1. Ph – CH = CH – CH2OH    
  2. Ph – CH2CH2 – CH2OH    
  3. Ph – CH2 – CH2 –stack C with table row cell O end cell row cell vertical line vertical line end cell end table on top– OH    
  4. None    

The correct answer is: Ph – CH = CH – CH2OH
