(a)
Interpretation:
The longer bond has to be predicted between O-H hydrogen bond and O-H covalent bond.
Concept introduction:
Hydrogen bonding: It is an
This type of bonding does not sharing of electrons in a covalent bond; it is attraction between the positive and negative poles of charges atoms.
Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms.
(b)
Interpretation:
The stronger bond has to be predicted between O-H hydrogen bond or O-H covalent bond.
Concept introduction:
Hydrogen bonding: It is a electromagnetic attraction between polar molecules with hydrogen bonds to a larger atom (for example oxygen or nitrogen) atoms.
This type of bonding does not sharing of electrons in a covalent bond; it is attraction between the positive and negative poles of charges atoms.
Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms.

(E) Label at least one representation of a covalent bond and at least one representation of anintermolecular force found in Figure 4.1. b. (E) Which are shorter and stronger: covalent bonds p intermolecular forces [circle one]?arrow_forwardPartial negative charge 8- Electrons are pulled toward oxygen. 8+ Partial positive charge The water molecule has a unique structure because of one side with more electrons than the other. This causes it to have one side that is more positively charged and the other more negatively charged. So lons are attracted to one side or the other depending their charge, this makes water. O A. A very poor solvent because other ions can't decide which side to be attracted to. O B. A very good solvent because ions are attracted to one side or the other. OC. Not a solvent at all, it cannot dissolve other materials. O D. Both a solvent and non solvent depending on the ions it is around and the possible bonds created.
