What to expect: This mock test covers key concepts from the Coordination Compounds chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.In the entity dichloridobis(ethane-1,2-diamine)platinum(IV) of the type MX2(L-L)2, which isomer shows optical activity? (NCERT section 5.4.2)
- A.Only the cis isomer
- B.Only the trans isomer
- C.Both isomers equally
- D.Neither isomer
-
2.Assertion (A): The nitrite ion and the thiocyanate ion are described as ambidentate ligands. Reason (R): These ligands possess two different donor atoms and can coordinate to the metal through either one of them.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
3.Assertion (A): The metal-carbon bond in metal carbonyls possesses both sigma and pi character due to synergic bonding. Reason (R): The metal donates a lone pair into the carbonyl carbon while carbon monoxide donates electrons from its filled orbital into a vacant metal orbital.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
-
4.The correct formula of the compound iron(III) hexacyanidoferrate(II) is:
- A.Fe4[Fe(CN)6]3
- B.Fe3[Fe(CN)6]4
- C.Fe[Fe(CN)6]
- D.Fe2[Fe(CN)6]3
-
5.Assertion (A): For tetrahedral complexes low spin configurations are rarely observed. Reason (R): The tetrahedral crystal field splitting is only about four ninths of the octahedral splitting, so the splitting energy is usually too small to force electron pairing.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
