Lipophilicity will increase with INCREASED halogen, and INCREASED hydrocarbyl substitution on the phenyl ring.

And so the most fat-soluble molecule is #(Cl)(H_3C)C_6H_4#.

#(HO)(H_3C)C_6H_4# has a polar hydroxyl group, and this should be least fat-soluble.....

Insecticides such as #"DDT"#, #"dichlorodiphenyltrichloroethane"#, when it was incorporated into the food-chain, tended to accumulate in fat tissues.
