There is a transfer of one or more valence electrons form one atom to another
Result through the sharing of electrons.
Measures the relative tendency of an atom to attract electrons to itself when chemically combined with other atoms.
Non-polar Covalent Bonding
Polar Covalent Bonding
Which of the following among the intermolecular forces is weakest?
Which of the following among the intermolecular forces is considered the strongest?
You are tasked for the dishwashing duties of the oily pans and utensils following your dinner of deep-fried food. First, you scrape excess food then rinse it with water. You noticed that the grease does not mix with water. What can you infer from this observation? Recall that the general rule for deciding if one substance is capable of dissolving another is “like dissolves like.”
When nonpolar liquid such as oil is mixed with water which is nonpolar, two separate layers form because the liquids will not dissolve into each other.
None of the choices are correct because oil is miscible or can dissolve with water.
Both a and b are correct
When a nonpolar liquid such as oil is mixed with water which is polar, two separate layers form because the liquids will not dissolve into each other.30sEditDelete
What do you call the dipole-dipole attraction between hydrogen atom and electronegative
elements F, O, and N?
What force of attractions involved between K+ and H2O when KCl interacts with H2O?
Which of the following describes why the boiling point of CH4 (-161.6 °C) is much lower than
that of HF (19.5 °C)?
The boiling point is higher in HF because the hydrogen bonding in HF is stronger than the attractive forces in CH4.
The boiling point is higher in HF because CH4 is polar.
The boiling point is higher in HF because of the weaker ion-dipole interactions in CH4.
The boiling point is higher in HF because of the weaker dipole-dipole interactions in CH4.30sEditDelete
Group of biological macromolecules that are composed out of carbon (C), hydrogen (H),oxygen (O), nitrogen (N), and phosphorus (P)

monosaccharides, lipids, polysaccharides, and proteins
carbohydrates, lipids, nucleic acids, and protein
proteins,DNA, RNA, and steroids30sEditDelete
