Question

According to the valance bond theory,

which of the following orbitals undergo Overlapping to form H-F?

(a) 2Pz -orbital from hydrogen with 1S- orbital from fluorine.

(b) 2Px- orbital from fluorine with 1S- orbital from hydrogen.

(C) 2Pz- orbital from fluorine with 1S- orbital from hydrogen.

(d) 2S- orbital from Hydrogen with 1S- orbital from hydrogen.

Answer 1

Answer:

the answere is c bcoz fluorine's electronic configuration is [He]2s²2px²2py²2pz¹ and hydrogen's 1s¹. Therefore 2pz¹ orbital of fluorine will ovelapp with 1s¹ orbital of hydrogen to form a bond .
