Which one of the following statements is correct?
Options
- AHybrid orbitals do not form bonds
- BLateral overlap of p -orbitals or p - and d -orbitals produces -bonds
- CThe strength of bonds follows the order _ p-p < _ s-s < _ p-p
- Ds-orbitals do not form bonds
Correct answer
B. Lateral overlap of p -orbitals or p - and d -orbitals produces -bonds
Step-by-step solution
(a) Hybridised orbitals show only head on overlapping and thus form only bonds. They never form bonds. (c) Head on overlapping is stronger than lateral or sideways overlapping. Therefore, the strength of bonds follows the order _ -p _ array c lateral overlapping array < _ s-s < _ s-p < _ -p _ head on overlapping of same shell (d) s-orbitals are spherically symmetrical and thus show only head on overlapping and form only bonds.
