WebIn effect, the chlorine atoms are helping to further spread out the electron density of the conjugate base, which as we know has a stabilizing effect. In this context, the chlorine substituent can be referred to as an electron-withdrawing group.

Up to 2/3s of our harmful exposure to chlorine is due to inhalation of steam and skin absorption while showering. A warm shower opens up the pores of the skin and allows for accelerated absorption of chlorine and other chemicals in water.
WebAbstract. The corrosion of twenty-five metals and alloys by liquid and gaseous fluorine was studied. The liquid corrosion tests were performed at --320 tained F and exposure ranged from 5 hours to 3 days. Expcsures to gaseous fluorine were made at apprcximately 80, 400, 700, and 1000 tained F. Expcsure times were generally 5, 24, and 120 hours. WebThis is basically asking about the inductive effect. Because F is more electronegative it is better at stabilizing the carboxylate as it can 'pull' electron density towards it better than Cl can. So the proton closer to the F (on the left) is more acidic because the conjugate base is more stable. It's not stabilizing the proton it's stabilizing ...
