The CORRECT statement(s) among the following regarding this adsorption is/are

TestHub · Accepted Answer

The electron from metal will be transferred to the LUMO, i.e., one of the π 2 p ∗ ​ MOs. This in turn results in lowering of bond order and hence lengthening of the bond. As there is realignment of electrons during this process, it is chemisorption. Adsorption is always exothermic.
