Is alcohol a polar or non-polar molecule?
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. See: http://www.elmhurst.edu/~chm/vchembook/162othermolecules.html
What is the chemistry of alcohol?
Alcohol is a class of organic compounds characterized by the presence of a hydroxyl (-OH) functional group attached to a carbon atom. The general chemical formula for alcohol is R-OH, where R represents an alkyl group. The properties and reactivity of alcohols depend on the structure of the alkyl group and the presence of any additional functional groups.
What is ethanol polarity?
Ethanol is a polar molecule due to the presence of the hydroxyl group (–OH), which results in an uneven distribution of charge. This polarity allows ethanol to dissolve in water and interact with other polar substances.
Is C17H35COOH a polar molecule?
Yes, C17H35COOH is polar because it contains a carboxyl group (–COOH) which is a polar functional group due to the electronegativity difference between the oxygen and carbon atoms.
What functional group is highly polar and may act as a weak acid?
Carboxyl groups are highly polar and can act as weak acids.
Which is a polar functional group found in alcohols?
The functional group in alcohols is the hydroxyl -OH.
WHAT group impart polarity to alcohols?
The group that imparts polarity to alcohols is the hydroxyl group (-OH). This functional group is highly polar due to the electronegativity difference between oxygen and hydrogen, which creates a dipole moment. As a result, alcohols can form hydrogen bonds with water and other polar substances, contributing to their solubility in water and other polar solvents.
What functional group is always polar?
The hydroxyl group (-OH) is always polar due to the significant electronegativity difference between the oxygen and hydrogen atoms. This polarity allows molecules containing hydroxyl groups, such as alcohols, to form hydrogen bonds with water, enhancing their solubility in polar solvents. Other functional groups, like carbonyls and amines, can also be polar, but the hydroxyl group is a classic example of a consistently polar functional group.
Why are alcohols soluble in polar solvents while hydrocarbons are not?
Alcohols contain a hydroxyl (-OH) group which can form hydrogen bonds with polar solvents, making them soluble. In contrast, hydrocarbons lack these polar functional groups and interactions, leading to poor solubility in polar solvents.
What functional group does alcohal belong to?
alcohol homologous series OH is the functional group of ethanol
Which functional group does isopropanol contain?
Isopropanol, also known as isopropyl alcohol, contains a hydroxyl functional group (-OH). This group is characteristic of alcohols, making isopropanol a type of alcohol. The presence of the hydroxyl group is responsible for its polar nature and ability to engage in hydrogen bonding.
Why alcohols are comparatively more soluble in water than hydrocarbons of comparable molecular masses?
Alcohols are more soluble in water than hydrocarbons of comparable molecular masses due to the presence of the hydroxyl (-OH) group, which can form hydrogen bonds with water molecules. This polar functional group enhances the ability of alcohols to interact with water, increasing their solubility. In contrast, hydrocarbons are non-polar and do not form such interactions, making them less soluble in polar solvents like water. Additionally, the overall structure of alcohols allows for better integration into the hydrogen-bonding network of water.
A compound contains hydroxyl groups as its predominant functional group what is true concerning this compound?
The compound is likely an alcohol, as hydroxyl (-OH) groups are the functional group in alcohols. It may have properties such as high solubility in water, the ability to form hydrogen bonds, and potentially be used as a solvent or in various chemical reactions. Additionally, alcohols can participate in dehydration reactions to form alkenes.
What accounts for the similar physical properties of alcohols?
The similar physical properties of alcohols are primarily due to their common functional group, the hydroxyl group (-OH), which influences their hydrogen bonding capabilities. This leads to higher boiling and melting points compared to hydrocarbons of similar molecular weight. Additionally, the polarity of the hydroxyl group contributes to their solubility in water, making alcohols generally more hydrophilic than non-polar compounds. These factors collectively result in the characteristic physical properties observed across various alcohols.
What functional group makes a carbohydrate polar?
The hydroxyl (-OH) functional group in carbohydrates makes them polar. This group is present in monosaccharides like glucose and fructose, adding polarity to the molecule.
Give an example of how a functional group can affect the properties of an organic compound?
An atom or group of atoms which gives the specific properties to an organic compound is a functional group or The active part of an organic molecule involved in a chemical reaction is known as the functional group. Examples are, 1-Alcohol R-OH, 2-Carboxylic acid R-COOH, 3-Ether R-O-R, e.t.c
