A long chain of hydrocarbon bonded to COOH is a FATTY acid.
        
                    
             
        
        
        
Kp= (COCl2)/[(CO)(Cl2)]= 1.49 x 10^8
1.49 x 10^8= (COCl2/((2.22x10-4)(2.22x10-4))
COCl2= 1.49x10^8 x ((2.22x10-4)(2.22x10-4))= 7.34 atm
        
             
        
        
        
Well none since molecules are a group of two or more atoms electrically bonded with one another. However, there are gases that does not naturally bond due to their stability and can be found in nature as pure elements. But these are not considered as molecules. 
(By the way, these gases are the noble gases that can be found on the last column of the periodic table)
