Question

what is the EAN of Mn2(CO)10???

Answer 1

Answer:

36

Explanation:

The formula for effective atomic number(EAN) is => Z - O.S + 2CN

here,

Z=atomic number

O.S=oxidation state

CN=coordination number

So, FOR 2 Mn

Z=2×25

O.S=0

CN=10 (for 10 CO ) + 1 (for 1 Mn-Mn sigma bond)

Thus CN = 11

EAN = 2×25 - 0 + 11×2

50+ 22

72

Thus 72 for 2 Mn

or 72/2 for 1Mn

= 36
