compounds like CCL4,SiCl4, GeCl4 but down the group +2 oxidation state becomes more stable due to their inner pair effect so SnCl2 and PbCl2.
2. Eutrophication is the presence of excess nutrients in water bodies.
Release of nutrient rich sewage and industrial effluents lead to introduction of nitrogen and phosphorous in water body.
Harmful effects:
1. Plant and animal biomass increases
2. rate of sedimentation increases, shortening the life span of lake.
3. Turbidity increases.
4.Anoxic conditions[deprived of dissolved oxygen] may develop
