Covalent compounds can be subdivided into polar and no polar compounds. In water, a polar molecule, the hydrogen electrons are not shared equally with the oxygen atoms; this results in a polar bond. Oxygen due to it's greater electro negativity pulls the electrons closer to its nucleus.
The Treaty of Versailles was the main causes of World War II due to the following reasons,Germany had to pay back 33 billion after WWI and forced to accept sole blame for the war in order to justify the reparations.
The Treaty of Versailles sowed the seeds of instability in Europe in the sense that it created a sense of power imbalance and weakened Germany (which led to World War 2).ut perhaps the most humiliating for Germany was the War Guilt Clause, where Germany had to accept blame for starting WWI. Overall, the Treaty of Versailles was intended to spread democracy in Europe, but there was a retreat from democracy more so than ever.
