CH3CH(OH)CH3, or isopropanol, is less polar than water. While isopropanol contains a hydroxyl group (-OH) that can form hydrogen bonds, its overall molecular structure, including the presence of two hydrocarbon groups (methyl groups), reduces its polarity compared to water. Water's highly polar nature is due to its bent shape and strong hydrogen bonding capabilities, making it more polar than isopropanol.
What else can I help you with?
Is melting ice more or less dense than polar water?
Except at EXTREME pressures (like over 200 MPa), ice is less dense than liquid water. In the case of polar water this is even more the case since polar water has a fair amount of salt dissolved into it, raising it's density, while the ice is nearly pure water.
Why are glycerophospholipids more soluble in water than tricylglycerols?
Glycerophospholipids have a polar head group that interacts with water molecules, making them soluble in water. Triglycerides lack this polar head group, which makes them less soluble in water.
Which is more polar 2-propanol or water?
Water is more polar than 2-propanol because it has a greater difference in electronegativity between oxygen and hydrogen atoms, leading to a larger dipole moment. 2-propanol also has a dipole moment due to the hydroxyl group, but it is less polar than water.
Does polar water diluted by melting ice become more less dense than?
When polar water is diluted by melting ice, the overall density of the water can decrease. Ice is less dense than liquid water, which is why it floats; when it melts, it adds water to the surrounding liquid without significantly increasing the mass. However, the temperature and salinity of the surrounding water can also affect density, but generally, melting ice leads to a less dense mixture compared to the original polar water.
Are polar or non polar substances more likely to be found in high concentrations in the bloodstream of a vertebrae?
Polar substances are more likely to be found in high concentrations in the bloodstream of vertebrates. This is because the blood is primarily composed of water, which is a polar solvent that readily dissolves polar substances. Non-polar substances, on the other hand, tend to be less soluble in water and may require specific transport mechanisms or carrier proteins to circulate in the bloodstream.

Why iodine is more soluble in cl but less soluble in water?
Iodine is not soluble in water because iodine is nonpolar and water is polar. According to the "Like dissolve like" expression, nonpolar substances are soluble with nonpolar substances and polar substances are soluble with polar substances, but nonpolar substances are not soluble with polar substances.
Are covalent bonds more soluble than ionic bonds?
Covalent bonds are generally less soluble in water compared to ionic bonds. Ionic compounds dissolve in water because of the attraction between the ions and the polar water molecules. In contrast, covalent compounds are usually nonpolar or have weaker polar bonds, making them less likely to interact with polar water molecules and dissolve.
Is thymol non-polar?
Thymol is considered to be moderately polar due to the presence of hydroxyl (OH) groups, which can participate in hydrogen bonding. It is more polar than non-polar compounds like hydrocarbons, but less polar than highly water-soluble compounds.

Why is water more cohesive than alcohol?
Water is more polar than alcohol is. The molecule contains two strongly polar O-H bonds and no other bonds. A molecule of alcohol contains one highly polar O-H bond, one somewhat less polar C-O bond, and a nonpolar hydrocarbon segment.
Why is glucose more soluble in water than cyclohexanol?
Glucose is more soluble in water than cyclohexanol because glucose is polar. In contrast, cyclohexanol is mostly nonpolar and therefore less soluble in water.
What is more polar ethanol or water?
Water is more polar than ethanol. This is because water has stronger hydrogen bonding due to the presence of more hydrogen-bonding sites (two hydrogen atoms and one oxygen atom), making it a better solvent for polar substances. Ethanol is also polar but has weaker hydrogen bonding compared to water.
