What makes a molecule polar? What determines if an atom is chemically reactive? For example, is neon (the gas once lighting the Las Vegas strip) chemically reactive? Explain. How do valence electrons affect elements bonding with other elements?
Why is ethyl acetate a polar solvent? Explain. Why does sugar dissolve but not dissociate in water even though it is a polar molecule? Explain very briefly why the boiling point of H2O is higher than that of H2. What is the definition of chirality?
A polar molecule is mostly positive on one side and mostly negative on the other. This difference allows the polar molecule...

What is a polar molecule? Types of Bonds: There are two main types of strong bonds that occur between molecules, covalent and ionic. Ionic bonds occur when one atom donates electrons to another. Covalent bonds occur when two atoms share electrons. ...
the higher a molecule's boiling point is in its liquid state. Dipole moment is a term used to describe the overall polarity of a molecule. Hydrogen chemical bonds have abnormally strong polar bonds, which explains why water boils at 100 degrees Celsius, whereas similar molecules boil at lower...
The chemical structure of water makes it an excellent medium for life.Water is actuallyquite simple,bus the way the water molecule is formed gives water its unique properties.The water molecule is made up of two hydrogen atoms and ane oxygen atom.They form a polarmolecu...
What Is The Difference Between A Permanent And A Temporary Dipole? Permanent dipolesarise due to the difference in the electronegativity (relative attraction towards electrons) between two atoms inside a molecule. Let’s consider hydrogen fluoride as an example. The electronegativity of fluorine is gre...
For instance, CO2, a linear molecule, has its dipole moment canceled out due to its symmetrical dipoles while the bent structure of H2O makes the dipole asymmetric and thus they have the net dipole moment. To determine the dipole moment, one must draw the Lewis dot structure, indicate ...
Nonpolar molecules do not dissolve easily in water. They are described as hydrophobic, or water fearing. When put into polar environments, such as water, nonpolar molecules stick together and form a tight membrane, preventing water from surrounding the molecule. Water's hydrogen bonds create an en...
