Which of the following functional groups is associated with acids?
Carboxylic Acids. Organic acids such as acetic acid all contain a functional group called a carboxyl group. via
Which of the following functional groups is the most important for a cell to perform life quizlet?
The seven chemical groups most important in biological processes are the hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, phosphate, and methyl groups. The first six groups can act as functional groups; they are also hydrophilic and thus increase the solubility of organic compounds in water. via
Which of the following functional groups is associated with the release of energy when removed from the carbon skeleton with water?
ATP stores the potential to react with water, thereby removing a phosphate group and releasing energy for cellular processes. via
What are the 7 functional groups?
Hydroxyl, sulfhydryl, carbonyl, carboxyl, amino and phosphate groups. via
What is the name of the COOH functional group?
The carboxyl (COOH) group is so-named because of the carbonyl group (C=O) and hydroxyl group. The chief chemical characteristic of the carboxylic acids is their acidity. via
Which of the following is a sulfhydryl functional group?
Sulfhydryl Group Structure
The molecular formula for a sulfhydryl group is R-SH, which is similar to another functional group: alcohols (R-OH). The only difference between these groups is the presence of a sulfur atom versus an oxygen atom. via
What element is always in organic chemistry?
Carbon is the central element to all living organisms. It is the basis to all life on earth. By studying carbon and organic compounds, scientists can learn more about life, the human body, and how it works. Most organic molecules are made up of long rings or chains of carbon atoms with atoms of other elements attached. via
Which of the following examples best describes a unique functional property of the carboxyl group?
Which of the following examples best describes a unique functional property of the carboxyl group? The covalent bond between oxygen and hydrogen is so polar that hydrogen ions tend to dissociate from oxygen reversibly. the replacement of the -OH of a carboxyl group with hydrogen. via
How do you identify a carboxyl group?
Carboxyl groups are functional groups with a carbon atom double-bonded to an oxygen atom and single bonded to a hydroxyl group. The molecular formula is COOH. Carboxyl groups missing a hydrogen atom are de-protonated and ionized. Ionized carboxyl groups act as acids, require less energy and are more stable. via
What's the difference between glucose and hexanoic acid?
Glucose and hexanoic acid each contain six carbon atoms, but they have completely different properties. Glucose is a nutrient found in food; hexanoic acid is poisonous. via

How do you know if a functional group is acidic or basic?
Charged, accepts H+ to form NH3+. Since amino groups can remove H+ from solution, they are considered basic. Charged, ionizes to release H+. Since phosphate groups can release H+ ions into solution, they are considered acidic. via
How do you know if a functional group is polar or nonpolar?
When 2 equally strong (electronegative) atoms are bound, the sharing of electrons will be equal between them. If a functional group is composed of an atom that has strong-weak bonds, the group will be polar. via
Which functional group would act as a base in water?
Amino groups can also act as bases, which means that the nitrogen atom can bond to a third hydrogen atom as shown in the image below. Once this occurs, the nitrogen atom gains a positive charge and can now participate in ionic bonds. The amine functional group can exist in a deprotonated or protonated state. via
