Chemistry · Periodic Classification
Match the electronic configuration of elements in List-I with their first ionization enthalpy (ΔiH in kJ mol-1) given in List-II: List-I (Configuration): (a) 1s22s2, (b) 1s22s22p4, (c) 1s22s22p3, (d) 1s22s22p1 List-II (ΔiH): (p) 801, (q) 899, (r) 1314, (s) 1402
- 1(a) → (s), (b) → (p), (c) → (q), (d) → (r)
- 2(a) → (p), (b) → (s), (c) → (r), (d) → (q)
- 3(a) → (p), (b) → (r), (c) → (s), (d) → (q)
- 4(a) → (q), (b) → (r), (c) → (s), (d) → (p)✓
Correct answer
(a) → (q), (b) → (r), (c) → (s), (d) → (p)
