Therefore,  if  free  chlorine  gas  comes  in  contact  with  these  mole- 
cules, it  cannot  attack  the  propenyl,  as  this  is  really  substituted  by  the 
stearyl  and  oleyl.  Again,  the  stearyl  and  oleyl  cannot  be  acted  on  by 
the  chlorine  in  their  acid  nuclei,  according  to  the  analogy  established 
by  the  formation  of  dichloracetic  acid,  as  will  be  seen  herein  :

The  chlorine  mast  act,  therefore,  on  the  hydrocarbon  appendices^ 
Ci7H3g  and  C15H31,  substituting  therein  the  relative  hydrogens  by  chlo- 
rine, resulting  in  a  molecular  position  as  shown  below :
