Answers:electron negativity is the energy needed to remove 1 electron to form negative ions.the difference between polar and non polar covalent bonds is that non polar takes within the same element but polar takes with different elements.
Answers:Molecular polarity is dependent on the difference in electronegativity between atoms in a compound and the asymmetry of the compound's structure. For example, water is thought to be polar because of the unequal sharing of its electrons. However, methane is considered non-polar because the carbon shares the hydrogen atoms uniformly.
Answers:Electronegativity is the tendency of an atom to gain electron to itself in a molecule A non polar covalent bond is a molecule that has a covalent bond and doesn't have the differences of electronegativity or the differences is canceled due to the arrangement of the atom inside the molecule. for example Cl-Cl is a non-polar molecule because it does not has any electronegativity differences because it consists of only one molecule. H-Cl is a polar molecule because Cl is more electronegative thus the molecule is more negative in the Cl side. (+)H-Cl(-). It is a polar molecule. CH4 does have electronegativity differences but the arrangements cancel the effect so it is a non-polar molecule H I H--C--H I H The ectronegativity is canceled due to the balance of arrangement left and right, up and down. But if the any molecule that has one lone-pair, it is definitely o polar molecule. If two, look at the arrangement. You must look at the electronegativity chart to know the electronegativity of each atom.
Answers:A single molecule can have both nonpolar and polar bonds; therefore, it is not recommended you talk about the interaction of different types of bonds to describe physical properties of different molecules. Instead just state that the molecule is either polar, nonpolar, or slightly polar. In any case, solubility will be more likely when the polarity of the two molecules are as closely related to each other. Nevertheless, a small amount should still go in solution.
