Question

According to molecular orbital theory, which of the following will NOT be viable?

विकल्प

• He₂

• Li₂

• \[\ce{O^+_2}\]

• \[\ce{O^-_2}\]

Answer 1

He₂

Explanation:

He₂: B.O. = `(2 - 2)/2` = 0

Li₂: B.O. = `(4 - 2)/2` = 1

\[\ce{O^+_2}\]: B.O. = `(10 - 5)/2` = 2.5

\[\ce{O^-_2}\]: B.O. = `(10 - 7)/2` = 1.5

Hence, He₂ will not be viable.
