\({SnCl}_2\) has a bent or V-shaped geometry due to lone pair on Sn.
Count molecules with similar bent geometry:
- \({SO}_2\) : bent
- \({H}_2{O}\) : bent
- \({NO}_2\) : bent
- \({O}_3\) : bent
- \({PbCl}_2\) : bent
Other molecules like \({HgCl}_2\), \({BeCl}_2\), \({XeF}_2\) have linear or different geometries.
Total = 5 molecules.
Match the following molecules with their bond angles:
List-I (Molecule) | List-II (Bond angle) | ||
---|---|---|---|
A) \(\mathrm{NH}_3\) | I) 102.2° | ||
B) \(\mathrm{O}_3\) | II) 107.8° | ||
C) \(\mathrm{S}_6\) | III) 93.6° | ||
D) \(\mathrm{PH}_3\) | IV) 117° |
