JEE MAIN - Chemistry (2025 - 2nd April Evening Shift - No. 8)
Which of the following statements are true?
(A) The subsidiary quantum number $l$ describes the shape of the orbital occupied by the electron.
(B) _2nd_April_Evening_Shift_en_8_1.png)
is the boundary surface diagram of the $2 \mathrm{p}_x$ orbital.
(C) The + and - signs in the wave function of the $2 p_x$ orbital refer to charge.
(D) The wave function of $2 \mathrm{p}_x$ orbital is zero everywhere in the $x y$ plane.
Choose the correct answer from the options given below :
(A) and (B) only
(B) and (D) only
(C) and (D) only
(A), (B) and (C) only
Explanation
(A) Azimuthal quantum number ( $\ell$ ) indicates the shape of orbital occupied by the electron

(C) The + and - sign in the wave function of $2 p_x$ orbital refer to the sign (Phase) of the wave function, not the charge
(D) The wave function of $2 p_x$ orbital will be zero in yz plane (Nodal plane).
