Per NCERT §2.6.2 + Fig. 2.14, how many p-orbitals exist in a given p-subshell, and what shape do they have?
AOne p-orbital, spherical
BThree p-orbitals (p_x, p_y, p_z) — each shaped as two lobes (dumbbell) on either side of a nodal plane through the nucleus
CFive p-orbitals, cloverleaf
DTwo p-orbitals, ring
Answer & Solution
Correct answer: B. Three p-orbitals (p_x, p_y, p_z) — each shaped as two lobes (dumbbell) on either side of a nodal plane through the nucleus
Per NCERT §2.6.2, l = 1 gives 2l+1 = 3 p-orbitals: p_x, p_y, p_z. Each is dumbbell-shaped along its axis, with a nodal plane.
