Concept explainers
Interpretation:
The effect of electronegativity values on polarity of a bond is to be discussed.
Concept introduction:
- Ionic bond
- Chemical bond
- Coordinate bond
Answer to Problem 5RQ
If electronegative difference between the atoms is zero then pure covalent bond is formed.
If it is intermediate, then polar covalent bond is formed.
If the difference is large, ionic bond is formed.
Explanation of Solution
Ionic bonds are formed when there is complete transfer of electrons from one atom to another forming the bonds.
Covalent bond is formed by sharing of electrons between the atoms forming the bonds
Polar covalent bond is formed between two different atoms.
Non-polar covalent bond is between two same atoms.
Thus, electronegative difference value depicts which type of bond is formed between two atoms.
Thus, electronegative values are helpful in determining the polarity of bond.

- 4. a) Give a suitable rationale for the following cyclization, stating the type of process involved (e.g. 9-endo-dig), clearly showing the mechanistic details at each step. H CO₂Me 1) NaOMe 2) H3O® CO₂Mearrow_forward2. Platinum and other group 10 metals often act as solid phase hydrogenation catalysts for unsaturated hydrocarbons such as propylene, CH3CHCH2. In order for the reaction to be catalyzed the propylene molecules must first adsorb onto the surface. In order to completely cover the surface of a piece of platinum that has an area of 1.50 cm² with propylene, a total of 3.45 x 10¹7 molecules are needed. Determine the mass of the propylene molecules that have been absorbed onto the platinum surface.arrow_forwardChem 141, Dr. Haefner 2. (a) Many main group oxides form acidic solutions when added to water. For example solid tetraphosphorous decaoxide reacts with water to produce phosphoric acid. Write a balanced chemical equation for this reaction.
