Covalent compounds form when atoms that have similar electronegativity values form covalent chemical bonds. When a covalent compound dissolves in water, it does not dissociate into ions. Because there are no free electrons or ions in the water (electrolytes) dissolved covalent compounds can’t conduct electricity. What compounds conduct electric currentRead More →

Ionic bond is much stronger than covalent bond because it involves complete transfer of electrons because of which there is formation of cation and anion and there exist huge electrostatic forces of attraction. They also have high melting and boiling point which proves that the ionic bond is very strong.Read More →

Alkene decolorizes bromine water so it is often used as a test for unsaturated hydrocarbon. What Decolourises bromine solution quickly? Alkenes decolourise bromine solution rapidly, alkanes do not. Alkanes are formed from the reaction of an alkene with hydrogen. What does bromine water react with? The most common compounds thatRead More →

Since molecular compounds are composed of neutral molecules, their electrical conductivity is generally quite poor, whether in the solid or liquid state. In solid form, an ionic compound is not electrically conductive because its ions are unable to flow (“electricity” is the flow of charged particles). Are ionic compounds solubleRead More →

Compounds occur when two or more atoms combine into a pure substance. These can be broken down into their constituent atoms. In chemical reactions the atoms of the reactants interact to form new substances. How are compounds formed and separated? When two distinct elements are chemically combined—i.e., chemical bonds formRead More →

For many solids dissolved in liquid water, the solubility increases with temperature. The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions. How do solubilities of most ionic compounds in waterRead More →

Quats (quaternary ammonium compounds) are potent disinfectant chemicals commonly found in disinfectant wipes, sprays and other household cleaners that are designed to kill germs. It is often the stuff that allows a product to claim to be antibacterial, as they are certified by the EPA as pesticides. Is quaternary ammoniumRead More →

All organic compounds, such as proteins, carbohydrates, and fats, contain carbon, and all plant and animal cells consist of carbon compounds and their polymers. Why is carbon present everywhere? Carbon especially likes to bond with other small atoms, including other carbon atoms. This makes it capable of forming long chainsRead More →

the colour of transition elements is due to the presence of unpaired electrons. cu+ is colourless as its outermost configuration is 3d10 …so there are no unpaired electrons which causes the colour . Is CU a Colourless ion? Cuprous ions (Cu+) is colourless because it has no unpaired electrons inRead More →
