`+ and - sign` of the lobes of `p_y` orbital represents.

For 4p_y orbital There have

The energy of an electron of 2p_y orbital is

The energy of an electron of 2p_(y) orbital is

Assertion : The opposite lobes of ap-orbital have opposite sign whereas opposite lobes of d-orbital have the same sign. Reason : The opposite lobes of a p-orbital have opposite charge whereas opposite of lobes of d- orbital have the same charge.

Choose the correct statement. (1) d_(yz) orbital lies in the xz plane. (II) P_(z) orbital lies along x-axis. (III) Lobes of P_(x) orbital are at 90° with z-axis (IV) Lobes of d_(xy) orbital are at 90° with z-axis.
