NEET 2018 · ChemistryVSEPR shapePrevious Year Question
In the structure of , the number of lone pairs of electrons on the central atom Cl is:
Answer: (B) Two. \textbf{Answer:} (B) Two \textbf{Solution:} Cl in has 7 valence electrons; 3 are used in bonds to three F atoms, leaving 4 non-bonding electrons = 2 lone pairs.
- A.Four
- B.Two✓
- C.One
- D.Three
Correct Answer
(B) Two
Solution & Explanation
\textbf{Answer:} (B) Two \textbf{Solution:} Cl in has 7 valence electrons; 3 are used in bonds to three F atoms, leaving 4 non-bonding electrons = 2 lone pairs. This gives an (T-shaped) molecule with two lone pairs on Cl.
