(i) What is common between `d_9xy) and d_(x^(2) - y^(2))` orbitals ? (ii) What is the difference between them ? (iii) What is the angle between the lobes of the above two orbitals ?

Explanation

(i) Both have identical shape, consisting of four lobes.
(ii) Lobes of `d_(x^(2) - y^(2))` lie along the x and y-axes while those of `d_(xy)` lie between x and y-axes
(iii) `45^(@)`
