Question

The molecular orbital electronic configuration of HF molecule is _________

(a) 1s^2 2s^2 σspx^2 [2py^2 2pz^2] σspx*

(b) 1s^2 2s^2 σspx^2 [2px^2 2py^2] σspx*

(c) 1s^2 2s^2 σspx^2 [2px^2 2pz^2] σspx*

(d) 1s^2 2s^2 σspx^2 [2px^4] σspx*

I had been asked this question during an internship interview.

I'm obligated to ask this question of Homonuclear and Heteronuclear Molecules topic in division Atoms to Molecules to Material’s for Engineers of Engineering Chemistry I

Answer 1

Correct option is (a) 1s^2 2s^2 σspx^2 [2py^2 2pz^2] σspx*

The best I can explain: HF molecule has 10 electrons and its electronic configuration is 1s^2 2s^2 σspx^2 [2py^2 2pz^2] σspx*.
