Electronegativity of an atom determines how it will share the electrons in a covalent bond. If an atom has a high electronegativity and it is bonded to an atom with a low one, the shared electrons will stay closer to the one with higher electronegativity. This molecule will be polar. If two atoms are bonded with similar electronegativities, the electrons will be shared evenly and it will be nonpolar. Nonpolar bonds are uncommon because there are many atoms with different electonegativities, so the chance that they are very close is low.
Basically kid, if you are using Holt Rinehart and Winston chapter test/quiz for covalent compounds, the answer is A) one atom usually attracts electrons more strongly than the other (varying electronegativities)
YAY!!

Is oxygen ionic polar covalent or non polar covalent?
Oxygen typically forms polar covalent bonds in most compounds due to its high electronegativity. However, in some cases, oxygen can also participate in ionic bonding when it gains or loses electrons to form ions.
What covalent bonds are most polar?
Bonds between two nonmetals that differ in electronegativity (EN) are usually polar. Electronegativity is the tendency of an atom to attract electrons. Nonmetals with EN differences of 0.5-1.6 form polar covalent bonds. The greater the difference, the more polar. If the EN difference is
Is cocoa ionic or covalent bond?
Cocoa primarily contains covalent bonds. Covalent bonds involve the sharing of electrons between atoms. In the case of cocoa, the molecules within its chemical composition are held together by covalent bonds.
Which of these pairs of elements would most likely form non-polar covalent bonds Al and Br or Zn and Br or Br and Br or H and H?
Both Br and Br and H and H form non-polar covalent bonds.
What are some household items that contain non-polar covalent bonds?
Some household items that contain non-polar covalent bonds are cooking oil, plastic containers, and gasoline. These substances consist of molecules with similar electronegativities, leading to shared electron pairs and non-polar covalent bonds.
Is oxygen ionic polar covalent or non polar covalent?
Oxygen typically forms polar covalent bonds in most compounds due to its high electronegativity. However, in some cases, oxygen can also participate in ionic bonding when it gains or loses electrons to form ions.
What covalent bonds used to form?
It is used to form molecules and various compounds. In fact, most of the bonds are covalent bonds.
Why are covalent compounds soluble in water?
The polar covalent compounds are easily soluble in water as HCl, HNO3, H2SO4, Glucose and most of the sugars, Sugar has many polar covalent bonds, in the C-O-H groups, and the molecules of sugar fit easily into the hydrogen bonded microstructure of liquid water.
What is true of most organic compounds?
Most of the organic compounds are solids, combustible, non polar and insoluble in water.

Is gasoline a primarily ionic compounds or convalent compounds?
Gasoline is primarily composed of covalent compounds. It is a mixture of hydrocarbons such as octane and heptane, which are made up of covalent bonds between carbon and hydrogen atoms. These covalent bonds are formed through the sharing of electrons between atoms.
What are some household items that contain non-polar covalent bonds?
Some household items that contain non-polar covalent bonds are cooking oil, plastic containers, and gasoline. These substances consist of molecules with similar electronegativities, leading to shared electron pairs and non-polar covalent bonds.
What molecules contain the most polar covalent bond CO2 H20 O2 H2 CH4?
Water (H2O) contains the most polar covalent bond as oxygen is highly electronegative compared to hydrogen, resulting in unequal sharing of electrons. This makes water a polar molecule. Conversely, methane (CH4) contains nonpolar covalent bonds as carbon and hydrogen have similar electronegativities, resulting in equal sharing of electrons. O2 and CO2 contain polar covalent bonds, but they are not as polar as the bonds in water.
What are covalent bonds used to form?
Covalent bonds are primarily used to form molecules by sharing electrons between two atoms. These bonds are strong and stable, making them ideal for building complex structures in organic compounds and other chemical substances.
Why do covalent compounds dissolve in ethanol not in water?
The polar covalent compounds are easily soluble in water as HCl, HNO3, H2SO4, Glucose and most of the sugars, Sugar has many polar covalent bonds, in the C-O-H groups, and the molecules of sugar fit easily into the hydrogen bonded microstructure of liquid water.
