[求助] 求准确全面地翻译两句英文

Since Fluorine is so electronegative and powerful inductive electron withdrawing substituent,it makes successive Chlorines worse donors to the Lewis Acid Catalyst,hence halogen exchange becomes progressively difficult.
There is also a decrease in steric assistance to ionization as each larger chlorine is replace by a smaller fluorine.

氟具有很强的电负性同时也是强吸电子诱导效应的取代基,使得氯不适合制备用于路易斯酸催化剂的五氟化锑。。。
