The oxidation state (n) and coordination number (C .N.) of Al and number of valence electrons around Al(N) in `Al_2Cl_6` are respectively

Options

A. 3,3,6
B. 3,4,8
C. 4,4,8
D. 3,4,6

Answer

B

Explanation

Given ,
`Al_2 Cl_6`
Structure of `Al_2Cl_6` is

Oxidation state of Al in `AlCl_3` , n is given by ,
2x - 6 =0
`rArr` 2x =6
n or x =+3
Coordination number of Al in `Al_2Cl_6` is given by ,
C.N=4( `therefore` each Al is bounded by 4 Cl)
Number of valence electrons around Al in `Al_2Cl_6` is ,
N=2 x 4 = 8
