Read the following carefully to mark the correct option out of the options given below: Statement I: Si−Si bond is weaker then Si−O bond. Statement II: Silicon forms double bonds with itself.
Assertion is true but reason is false.Due to smaller size of oxygen atom, Si−O bond is stronger than Si−Si bond.
Statement-I : A charged plane parallel plate capacitor has half interplanar region (I) filled with dielectric slab. The other half region II has air. Then, the magnitude of net electric field in region I is less than that in region II.
Statement-II : In a dielectric medium, induced (or polarized) charges tend to reduce the electric field.
Read the following and select one the correct answer.
Statement I: Boron always forms covalent bond
Statement II: The small size of B3+ favours formation of covalent bond
Statement - I: Cl− and Ca2+ are isoelectronic species. Statement - II: Isoelectronic species should have same charges.
