Is glucose hydrophobic?
GLUCOSE IS VERY DEFINITELY POLAR WITH OH (HYDROXYL) GROUPS ALL OVER IT, WHICH ARE THEMSELVES VERY POLAR. THE MOLECULE IS ALSO VERY UNSYMMETRICAL WHICH TENDS TO MAKE IT POLAR. THE FACT THAT GLUCOSE IS EXTREMELY SOLUBLE IN WATER (ANOTHER POLAR SUBSTANCE) SHOWS THAT GLUCOSE IS POLAR SINCE "POLAR DISSOLVES IN POLAR" AND "NONPOLAR DISSOLVES IN NONPOLAR" (LIKE WAX AND GASOLINE)
What is transesterification?
When a compound is 'esterified' it means that an ester group has been added to the molecule. This is accomplished via condensation of an alcohol and an acid. The reaction results in a hydroxyl group (OH) being replaced by an alkyl group (RO).Esterification changes a compound's water solubility, makes it more volatile, and often more aromatic.Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product.
Are non-polar molecules more attracted to other non-polar molecules or polar molecules?
Non-polar molecules are more attracted to other non-polar molecules.
Glucose dissolves in water because?
Glucose dissolves in water due to both the solute, Glucose, and the solvent, H2O, are both polar. Polar atoms have an uneven distribution of charges, so they can dissolve easily in other polar solvents. Non polar atoms, such as CH4, need a non-polar solvent to dissolve in. Non-polar means that the charge is evenly distributed, so non-polar atoms will not dissolve in polar solvents.
Does water readily dissolve most polar compounds?
yes, less than 5 ch2 groups per oh, or nh2 group dissolves in water more does not.
What is more polar methyl salicylate or salicylic acid?
salicylic acid (an acid) is more polar than methyl salicylate (an ester)
Is methyl chloride more polar than aldehyde?
yes methyl chloride is more reactive.
Is alcohol or carbonyl group more polar?
carbonyl group does not have hydrogen, it is a carbon double bonded to oxygen. by adding a nucleophile such as H- or water you can form an alcohol in an addition reaction.
Is 1-propanol polar?
Isopropyl alcohol is the common name of 2-propanol. The O in the hydroxyl group is more electronegative than the carbon/hydrogen atoms and exerts a greater pull on the electrons, which results in the slight polarity of the compound.
How does the size of the alkyl group in an alcohol affect the vigor of its reaction with sodium metal?
The larger the alkyl group, the less energeticthe reaction, because the hydroxyl groups are "diluted". byadding more alkyl groups, you decrease the concentrationof hydroxyl groups and therefore make the molecule less polar. thisdecreases the vigor of reaction with sodium metal.
Is OH Polar or Non- polar covalent?
The O-H bond is polar covalent. Very strongly polar because of the difference in electronegativity.
Is hexane an alcohol?
yes it is.
Why does AMINE group activate the benzene ring more than the hydroxyl group?
as nitrogen is less eletronegative than oxygen so the delocalisation of lone pair eletron to the benzene ring is more in case of amine compare to hydroxyl group
This is produced when one or more of the hydrogens in a hydrocarbon is replaced by a hydroxyl group?
alcohol
Is glycerol soluble in polar solvents?
polar, but be careful, because "glycerin" is nonpolar
What are the names of alcohol that have more than 4 hydroxyl group?
They are called polyhydric alcohol
A carbohydrate can be defined as a molecule?
that is an aldehyde or ketone and that has more than one hydroxyl group
