, orbital has a total of two nodal planes

, * orbital has one node in the xz-plane containing the molecular axis.

and orbital has one node in the plane which is perpendicular to the molecular axis and goes through the center of the molecule.

. ONE OR MOER THAN ONE of these four option(s) is (are) correct answer(s). • For each question, choose the option(s) corresponding to (all) the correct answer(s). • Answer to each question will be evaluated according to the following marking scheme: Full Mark : +4 If only (all) the correct option(s) is(are) chosen; Partial Marks : +3 If all the four options are correct but ONLY three options are chosen; Partial Marks : +2 If three or more options are correct but ONLY two options are chosen, both of which are correct; Partial Marks : +1 If two or more options are correct but ONLY one option is chosen and it is a correct option; Zero Marks : 0 If unanswered; Negative Marks : -2 In all other cases. For diatomic molecules, the correct statement(s) about the molecular orbitals formed by the overlap of two 2p z orbitals is(are) * orbital has one node in the xy-plane containing the molecular axis.
