Question

Which of the following is the best Lewis structure for BF3? F: F: : F F R F (A) (B) O C O A O D LL: LL: : O :L: LL .. L: : L - :L: ..

Answer 1

Electronic configuration of Boron = [he] 252261 So, boron has three electrons in valence shell Electronic configuration of fluorine [467252285 so fluorine has seven electrons isivalence shell. As we all koow that only valence electrons will participate in bond formation. in option -A [correct] correct] E eso Bolf :) Al fluorine has seven electrons and boron has three electron so option A is correct. option is incorrect, Boron has 4 electron (if de B he :) and one of the fluoresce has 6 electron. So it is incorrect .. (it)

option C is incorrect Boron has 5 electron according to structure in valence shell AO it is incorrect Option D is incorrect, (:F!) According to sturucture Boron has 5 electron invalesce shell and thro fluorine has belectron in valence shell so this option is incorrect.
