Explanation Lewis acid-base reaction of F − with BrF 3 : Lewis structure of F − ; Given species is F − . Atomic number of fluorine is 9 . The given species F − is formed by adding one electron. The total number of valence electron present in F − is eight. Lewis structure is same as F − is drawn as by placing all the eight electrons as dots around the symbol of fluorine with a negative charge. Lewis structure of BrF 3 ; Given species is BrF 3 . The total number of valence electron present in BrF 3 is calculated as shown below; Total number of valence electron = 1 Br ( 7 electron ) + 3 F ( 7 electron ) = 7 + 21 = 28 Skeletal structure for BrF 3 is drawn as shown below; Six electrons are used up in the skeletal structure. Twenty two electrons are left out. Six electrons are placed over fluorine atom each and two electrons is placed over bromine. Therefore, the Lewis structure of BrF 3 is drawn as; Reaction between BrF 3 and F − results in formation of BrF 4 − . This can be represented as shown below; F − + BrF 3 → BrF 4 − Lewis structure of BrF 4 − ; Given species is BrF 4 − . The total number of valence electron present in BrF 4 − is calculated as shown below; Total number of valence electron = 1 Br ( 7 electron ) + 4 F ( 7 electron ) + 1 e l e c t r o n = 7 + 28 + 1 = 36 Skeletal structure for BrF 4 − is drawn as shown below; Eight electrons are used up in the skeletal structure. Twenty eight electrons are left out. Six electrons are placed over fluorine atom each and two electrons are placed over bromine atom. Therefore, the Lewis structure of BrF 4 − is drawn as; Lewis acid-base reaction of Cl − with FeCl 3 : Lewis structure of Cl − ; Given species is Cl −
