Sharing of electrons always means its a covalent bond, and unequal means it is polar, so it is a polar covalent bond
Answer:
Explanation:
Speed of light = Wavelength x Frequency.
605 nm x Frequency = 3x10^8 m/s
6.05 x 10^-7 m x Frequency = 3x10^8 m/s
Frequency = 4.96 x 10^14 Hz
At 50 degrees Celsius and standard pressure inter-molecular forces of attraction are strongest in a sample of ethanoic acid.
Ethanoic acid has hydrogen atom bonded with a more electronegative atom; Oxygen. As a result, the molecule possesses strong intermolecular Hydrogen Bonds. Therefore; ethanoic acid, and all other carboxyllic acids have the tendency to form dimers.
Answer:
KMnO4,H3O^+,75°C
Explanation:
The conversion of cyclohexene to trans-1,2-cylohexanediol is an oxidation reaction. Alkenes are oxidized in the presence of potassium permanganate and acids to yield the corresponding diols.
These diols may also be called glycols. They are molecules that contain two -OH(hydroxyl) groups per molecule. The reaction closely resembles the addition of the two -OH groups of hydrogen peroxide to an alkene.
The bright color of potassium permanganate disappears in this reaction so it can be used as a test for alkenes.
The correct answer is:
Zinc and hydrochloric acid
Explanation:
Reactants are the opening materials in a chemical reaction. Reactants experience a chemical change in which chemical bonds are destroyed and new ones created to make products. In a chemical equation, reactants are posted on the left side of the arrow, while products are on the right side. If a chemical reaction has an arrow that points both left and right, then things on both sides of the arrow are reactants as well as products .And in above reaction Zinc and hydrochloric acid react and form zinc chloride.
