Question

which of the following is isoelectronic
a) CO2, NO2
b) NO2-, CO2
c) CN-, CO
d) SO2, CO2

Answer 1

it is option (c) .. CN- and CO .. both contains 14 electrons ..

Answer 2

Answer:

The correct answer is c) CN-, CO.

Explanation:

• Isoelectronic directs to two atoms, ions, or molecules that contain the identical electronic structure and the identical number of valence electrons.
• Two or more molecular entities exist expressed as isoelectronic if they have the exact number of valence electrons and the exact structure,
• In CO the number of electrons= 6 + 8 = 14 [Z of C and O = 8]Electronic configuration of molecular orbital of CO :CN- have even obtained 6 - 7 + 1 14 electrons and the configuration is identical to that of CO.CN- and CO exist isoelectronic
• The correct option is c) CN-, CO.
