Match List -I with List -II and select the correct answer using the code given below the Lists : List -I List-II (Compound/Molecule) (Shape of Molecule) A. CH3F 1. Trigonal planar B. HCHO 2. Tetrahedral C. HCN 3. Trigonal pyramidal D. NH3 4. Linear
Correct Answer: 2 1 4 3
Explanation:
HCHO: The carbon and and the oxygen are bonded through a double bond which counts as "one electron pair". Hence the molecule has three electron pairs and is trigonal planar.
