Question

Which of the following molecules have bond order equal to 1?

(a) NO, HF, HCl, Li2, CO

(b) H2, Li2, B2, HF, HCl

(c) Li2, B2, CO, NO,He2^+

(d) B2, CO, He2^+, NO, HF

I have been asked this question during an interview.

Query is from Homonuclear and Heteronuclear Molecules topic in division Atoms to Molecules to Material’s for Engineers of Engineering Chemistry I

Answer 1

Correct option is (b) H2, Li2, B2, HF, HCl

For explanation: He2^+ = 0.5, H2, Li2, B2, HF, HCl = 1, NO = 2.5, CO = 3.
