Match List-I with List-II and select the correct answer using the code given below the Lists :
List I (Compound/Molecule)
- ACHF3
- BHCHO
- CHCN
- DNH3
List II (Shape of Molecule)
- 1Trigonal planar
- 2Tetrahedral
- 3Trigonal pyramidal
- 4Linear
Code: A B C D
General KnowledgeChemistry
- A2 4 1 3
- B2 1 4 3
- C3 4 1 2
- D3 1 4 2
Explanation
CHF3 has a tetrahedral geometry around carbon, HCHO (formaldehyde) is trigonal planar, HCN is linear, and NH3 (ammonia) is trigonal pyramidal because of the lone pair on nitrogen. The matching is therefore A-2, B-1, C-4, D-3. Hence option B is correct.
