Question

Assign a formal charge to each atom in the following: a Formal charge for As = Formal charge for Cl = b Formal charge for As = Formal charge for F = c Formal charge for C =

Answer 1

Solution:- Formal Charge calculation Formal charge V-N-- 2 Where, V is the number of valence electrons of the neutral atom in isolation (in its ground state) N is the number of non-bonding valence electrons on this atom in the molecule B-is the total number of electrons shared in bonds with other atoms in the molecule C1-AsC Cl For atom "As", V-5, N- 2, B-6 Putting these values in above formula Formal charge@ As 5 2 - - 2 For atom "Cl", V-7, N 6, B-2 2 Formal charge @ Cl 7-6-一= 2 > For atom "As", V= 5, N = 0, B = 10 Formal charge@ As 5 0 - For atom "F", V-7, N 6, B 2 Formal charge @ F-7-6- 10 2 2 2 For atom "C", V-4, N 0, B-8 Formal charge@ C4 0- - 2
