The hydrophobicity of a molecule increases with longer contiguous chains of hydrocarbons. The -OH in 1-propanol is on the first of the three carbons, leaving the second and third carbons to form a larger hydrophobic molecular surface. In 2-propanol the OH on the central (second) carbon breaks up the overall surface hydrophobicity.
The reason for this is that the O is an electron drawing group. As such, O will have an effect on the bonds between the C it's connected to as well as each bond made by that C. Also, the closer O is to another atom in the molecule, the stronger the effect. In 1-propanol, O is further from the third carbon, thus having a lesser effect on the dipole moment of that carbon. In 2-propanol, the O effects the dipole moments of the first and third carbons equally.

What is the polarity of IF6?
IF6 is nonpolar. Due to the symmetrical octahedral shape and the arrangement of fluorine atoms around the central iodine atom, the individual dipole moments cancel each other out, resulting in a nonpolar molecule.
What organic compound is generally insoluble in water (hydrophobic)?
Lipids, such as fats and oils, are organic compounds that are generally insoluble in water because they are hydrophobic in nature. This is due to their non-polar nature, which makes them repel water molecules and form separate layers.
How can you determine the polarity of any bond?
The polarity of a molecule is quantified by its dipole moment. Calculating the dipole moment of a molecule (except if it is zero or completely non-polar) is not a simple task however, and it is generally determined experimentally.See the Related Questions to the left for how to determine the polarity of a molecule.
Is C22 H16 N4O polar?
Yes, C22 H16 N4O is a polar molecule due to the presence of polar covalent bonds within the molecule. The nitrogen and oxygen atoms contribute to its polarity by having different electronegativities and creating regions of partial positive and negative charges in the molecule.
What is the term for the overall direction of partial negative charge in a molecule having one or more dipoles?
The term for the overall direction of partial negative charge in a molecule with one or more dipoles is "dipole moment." It is a measure of the separation of positive and negative charges within a molecule and indicates the polarity of the molecule.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
Having an affinity for water?
Hydrophobic means to have an affinity for water.
What can static electricity push?
anything having the same polarity of charge.
What is the difference between hydrophobic and hydrophilic?
Hydrophilic is having an affinity for water; readily absorbing or dissolving in water.( love water) Hydrophobic is repelling, tending not to combine with, or incapable of dissolving in water.(hate water)
One word for hydrophobic and hydrophilic?
Amphipathic(1) Pertains to a molecule containing both polar (water-soluble) and nonpolar (water-soluble) portions in its structure.(2) Of, or relating to, a molecule having hydrophobic and hydrophilic regions.www.biology-online.org
What is the definition of polarity?
Polarity refers to the existence of two opposite or contrasting tendencies or characteristics. In chemistry, polarity refers to the separation of electric charge leading to the presence of positive and negative ends in a molecule.
What is hydrophobic and hydrophyilic?
the definition for hydrophobic is having little or no affinity for water. the definition for hydrophilic is having a strong affinity for water. All those compounds which have polar chemical structure possess affinity to water or can dissolve in water like alcohol, and those with non-polar structure are hydrophobic and cant dissolve in water like fat, oils etc.
Do phospholipids form micelles?
No, phospholipids do not typically form micelles. Micelles are formed by surfactant molecules, which have a hydrophobic tail and a hydrophilic head group. Phospholipids, while having hydrophobic tails and hydrophilic head groups, tend to form lipid bilayers, such as in cell membranes.
What do you mean by polarity in the covalent bonds?
Polarity in covalent bonds refers to the unequal sharing of electrons between atoms. This results in one atom having a partial negative charge and the other a partial positive charge. The greater the difference in electronegativity between the atoms, the more polar the bond.
What can you conclude about the advantage of the cell membrane having hydrophobic ends in the phospholipid bilayer?
Having hydrophobic ends in the cell membrane's phospholipid bilayer creates a barrier that prevents water-soluble molecules from freely crossing the membrane, maintaining cell integrity. This selective permeability allows the cell to control the movement of substances in and out, facilitating essential cellular processes. The hydrophobic nature also provides structural stability to the membrane.
How does hydrophobic and hydrophilic behaves in water?
hydrophilic substances are electrically polar in character, they possess a dipole. Intermolecular forces associated with this polarity attract (or are attracted by) the polar water molecules. Having sufficient energy, the water molecules can interpose themselves between and eventually surround the hydrophilic substance thus reducing the repulsive intermolecular forces acting between these hydrophilic molecules in their pure state... Energy and Entropy effects are driving the process...
What are particles with reversed magnetic polarity?
