Question

102. Which complex follow the Sidgwick EAN
rule (where atomic number of M = 24)
(1) [M(CO)6]-
(2) [M(CO)6]
(3) [M(CO)6]+
(4) All above follow EAN rule ​

Answer 1

Answer:

2)[M(CO)6]

Explanation:

For [M(CO)6] THE NO OF ELECTRONS IS 24+ ( 2*6)= 36 WHICH IS A NOBLE GAS ATOMIC NO (KRYPTON)

BUT FOR [M(CO)6]- THE NO ELECTRON IS 24+1+(2*6)=37

AND FOR THE [M(CO)6]+ THE NO IS 24-1+(2*6)=35

Answer 2

Answer:

1. [M(CO)6] -

EAN= 24+6×2+1

= 24+12+1= 37 (don't follow)

2. [M(CO)6]

25+6×2= 36 (follow EAN )

3. [M(CO)6]+=(24- 1)+6(2)

= 23+12

=35 (don't follow)
