When a highly electronegative atom is attached to a less electronegative atom, then the former one attracts the shared pair of electrons towards itself.
Such a molecule is polar molecule.
Polarity of molecule means the product of charge on molecule and the distance between the atoms.
What else can I help you with?
Is the molecule polar and hydrophilic or hydrophobic?
The polarity of a molecule determines whether it is hydrophilic (attracted to water) or hydrophobic (repelled by water). If a molecule is polar, it is typically hydrophilic, meaning it can dissolve in water. If a molecule is nonpolar, it is usually hydrophobic and does not mix well with water.
Is water a polar or nonpolar molecule?
Water is a polar molecule because it has a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms due to differences in electronegativity. This unequal sharing of electrons gives water a polarity, making it a polar molecule.
Why oil does not mix with water?
Oil is non-polar, meaning it does not have a charge, while water is polar, with positive and negative charges. This difference in polarity causes them to repel each other, preventing them from mixing. Additionally, oil molecules are larger and have weaker intermolecular forces, making them less likely to dissolve in water.
How does water become polar molecule?
Water becomes a polar molecule because of its bent molecular shape and the unequal sharing of electrons between the oxygen and hydrogen atoms. This results in a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms, creating a polar molecule.
Which is a factor that determines wether a molecule can cross the cell membrane?
Polarity
What causes the polarity of a water molecule?
the unequal sharing of electrons
How water acts as a lubricant and transport facilitator?
The polarity of the water molecule, which causes hydrogen bonds to form between the water molecules, is the characteristic that enables it to act as a lubricant.
What is a shorter answer for what causes polarity in a water molecule?
Asymmetrical distribution of electrons in the water molecule due to oxygen's higher electronegativity creates a partial negative charge near the oxygen atom and partial positive charges near the hydrogen atoms, leading to polarity.
How does a drawing of polarity water and the bond polarities make a major contribution to the overall molecular polarity look?
The polarity is a vector quantity. The resultant of the polarity of bonds determines the polarity of the molecule. In CO2 there is polarity between the two C-O but the polarity is equal and opposite in direction so CO2 doesn't have polarity. If the polarity of bonds is not cancelled then the polarity remains in the molecule.
How does the polarity of water molecules make water an effective solvent?
The polarity of the water molecule is what makes water a great solvent. It called the universal solvent.
What causes water to be a polor molecule?
Oxygen is a highly electronegative element that draws electrons towards itself causing an imbalance of charge and hence polarity.
What contributes to the polarity of a water molecule?
The polarity of a water molecule is due to its asymmetric shape, with the oxygen atom being more electronegative than the hydrogen atoms. This causes a partial negative charge on the oxygen atom and partial positive charges on the hydrogen atoms, creating a polar covalent bond.
What is the relationship between bond polarity and molecular polarity?
The relationship between bond polarity and molecular polarity is that the overall polarity of a molecule is determined by the polarity of its individual bonds. If a molecule has polar bonds that are not symmetrical, the molecule will be polar overall. If a molecule has nonpolar bonds or symmetrical polar bonds that cancel each other out, the molecule will be nonpolar overall.
Methanol or water which is higher polarity?
Water is higher in polarity compared to methanol because water is a polar molecule that contains polar covalent bonds due to the unequal sharing of electrons, while methanol is also polar but to a lesser extent due to the presence of a methyl group that reduces the overall polarity of the molecule.
What is the relationship between bond polarity and molecular polarity in chemical compounds?
The relationship between bond polarity and molecular polarity in chemical compounds is that the overall polarity of a molecule is determined by the polarity of its individual bonds. If a molecule has polar bonds that are not symmetrical, the molecule will be polar overall. Conversely, if a molecule has nonpolar bonds or symmetrical polar bonds that cancel each other out, the molecule will be nonpolar.
Is the molecule polar and hydrophilic or hydrophobic?
The polarity of a molecule determines whether it is hydrophilic (attracted to water) or hydrophobic (repelled by water). If a molecule is polar, it is typically hydrophilic, meaning it can dissolve in water. If a molecule is nonpolar, it is usually hydrophobic and does not mix well with water.
Why is carbon dioxide a non polar molecule while water is polar molecule?
Carbon dioxide is linear any polarity in the C=O bonds cancel each other out. Water is bent the polarity in the O-H bonds does not cancel
