Question

The electron geometry for BrX: (X is a group 7 element) trigonal planar tetrahedral trigonal bipyramidal pyramidal 5 pts Question 21 In the above molecule the formal charge on Brand X is: Br 1,X=0 Br=0, 0 Br=0.X=-1 Br=-1.X1

Answer 1

Ans:) If there is any doubt please ask in the comment section.

Ans: 20) Giren BrX₃ CX is halogen) The lewis structure is as Total valence election = 28 Bonding electron z 6 loan pair = 2 X: *! Hybridisation - Sp3d Then Geometry ies Trigonal bipyramidal & Coption 3) electonic Geometry is Fships. (Trigonal biperamidal) Ans: 21 formal charge is guien Fic = as valence – non-bonding - Bonding e Then, FC in Britz its as Br = 7/4 + 6 = 0. x = 7(6+2) = 0. Hence formal charge on Br =0, x=0, Coption 2

Thank you!
