JEE Main 2026 · 5 Apr · Shift 2, Chemistry question 52

Which of the following statement(s) is/are true ?

A. If two orbitals have the same value of (n+l)(n+l), the orbital with lower value of n will have lower energy.

B. Energies of the orbitals in the same subshell increase with increase in atomic number.

C. The size of 2px2p_x orbital is less than the size of 3px3p_x orbital.

D. Among 5f, 6s, 4d, 5p and 5d orbitals, none of the orbitals have 2 radial nodes.

Choose the correct answer from the options given below :

Answer and worked solution

Official answer: B

Each statement.

  • A: For equal n+ln+l, the orbital with lower n has lower energy. True.
  • B: Orbital energies decrease as atomic number increases (greater nuclear charge). False.
  • C: Size grows with n, so 2p is smaller than 3p. True.
  • D: Radial nodes are n−l−1n-l-1: 5f has 1, 6s has 5, 4d has 1, 5p has 3, and 5d has 2. False.

True: A and C.

(B)
