The formula for alcohol (ethanol) is CH3CH2OH. The OH group has a polar bond, as in water, because the oxygen atom is more electronegative than the hydrogen atom. This means the oxygen has a greater attraction for the shared electrons in the bond than the hydrogen does. The oxygen therefore carries a slight negative charge, leaving the hydrogen with a slight positive charge ie the bond is polar.
The polar OH group can then form hydrogen bonds with water, allowing the two substances to mix with each other.

Alcohol is a polar molecule because it contains an -OH (hydroxyl) group, which creates an uneven distribution of charge within the molecule. This results in a separation of positive and negative charges, making it polar.
All alcohols are polar.
Because of the strenght of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount. Starting with the four-carbon butanol the solubility of alcohols is starting to decrease. After the 7-carbon heptanol, alcohols are considered immiscible.
well i do know that the 0-H bond, which is called the hydroxyl group is a highly polar bond and that all alcohols (OH group attached) are highly polar.

Is lactic acid a polar or nonpolar molecule?
Lactic acid is a polar molecule. It contains both polar (-OH) and nonpolar (CH3) groups, but the presence of the polar -OH groups makes it an overall polar molecule.
Is bclh2 polar or nonpolar?
Bclh2 is nonpolar because it is a diatomic molecule composed of two sulfur atoms, which have similar electronegativities. This results in a symmetrical distribution of electrons, making the molecule nonpolar.
Is Fe2O3 polar or nonpolar?
Fe2O3 (iron oxide) is a nonpolar molecule because it has a symmetrical arrangement of its polar covalent bonds. The dipole moments in these bonds cancel each other out, resulting in a nonpolar overall molecule.
Why Is rubbing alcohol nonpolar?
Rubbing alcohol is nonpolar because it is composed mainly of isopropyl alcohol (C3H8O), which has a symmetrical molecular structure. The molecule does not have a significant difference in electronegativity between its atoms, resulting in a balanced distribution of electrons and no distinct positive or negative ends.
CH3Br polar or nonpolar?
CH3Br is a nonpolar molecule. Although the C-Br bond is polar due to the electronegativity difference between carbon and bromine, the overall molecule is nonpolar because of its symmetrical tetrahedral molecular geometry.
Is an polar molecule an ion?
No a molecule is a molecule, polar or nonpolar.
What is non polar molecule alcohol or mothballs?
Mothballs are nonpolar molecules. Alcohol can be polar or nonpolar depending on the specific type of alcohol.
Is CaOH02 a polar or nonpolar molecule?
non-polar molecule
Is a carbon dioxide molecule polar or nonpolar?
non-polar molecule
Is lactic acid a polar or nonpolar molecule?
Lactic acid is a polar molecule. It contains both polar (-OH) and nonpolar (CH3) groups, but the presence of the polar -OH groups makes it an overall polar molecule.
Is h2o molecule polar or nonpolar?
It is polar because it is asymmetrical
Is ch4 molecule polar?
No. CH4 is nonpolar.
Is Hsub2O a polar molecule or nonpolar?
I will assume Hsub2O is H2O [water] Water is a polar molecule.
Is bclh2 polar or nonpolar?
Bclh2 is nonpolar because it is a diatomic molecule composed of two sulfur atoms, which have similar electronegativities. This results in a symmetrical distribution of electrons, making the molecule nonpolar.
How can a molecule nonpolar overall and still contain polar bonds?
Yes, a molecule can be nonpolar when it contains polar covalent bonds, because think about it. if the molecule is linear in structure, and it has two equally polar bonds on either side, then the polarity will essentially cancel out, and it will become nonpolar.
Is Fe2O3 polar or nonpolar?
Fe2O3 (iron oxide) is a nonpolar molecule because it has a symmetrical arrangement of its polar covalent bonds. The dipole moments in these bonds cancel each other out, resulting in a nonpolar overall molecule.
