Solution


Q.

Identify the molecule (X) with maximum number of lone pairs of electrons (obtained using Lewis dot structure) among HNO3, H2SO4, NF3 and O3. Choose the correct bond angle made by the central atom of the molecule (X).                [2026]
1 102°  
2 107°  
3 116°  
4 120°  

Ans.

(1)

Number of lone pair in NF3 = 10

Bond angle in NF3≈102°
