Which Of The Functional Groups Shown Above Is Most Likely To Gain A Proton And Become Positively Charged? ›

which of the functional groups shown above is most likely to gain a proton and become positively charged? the amino group is most likely to gain a proton.

The amino group is most likely to gain a proton. An amino group acts as a base and can pick up protons from the surrounding medium, becoming positively charged.

Amino group and imino group are two functional groups associated with biomolecules that give them a positive charge.

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.

The hydroxyl group is most likely to gain a proton. The carboxyl group is most likely to gain a proton.

The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons). A proton is made of two Up quarks, with 2/3 positive charge each and one Down Quark with a negative 1/3 charge (2/3 + 2/3 + -1/3 = 1).

So, protons, or any atom or molecule with more protons than electrons, can be said to have a positive charge. Other positively charged particles include positrons and alpha particles.

Alcohols, Ethers, Amines, Thiols, Alkyl Halides. These functional groups are considerably more polar due to the greater difference in electronegativities between the bonding atoms. Stronger intermolecular forces are present in these functional groups due to the dipole-dipole interactions.

Location of Functional Groups

Each of the four types of macromolecules—proteins, lipids, carbohydrates, and nucleic acids—has its own characteristic set of functional groups that contributes greatly to its differing chemical properties and its function in living organisms.

Which functional group can pick up protons and raise the pH of the surrounding solution? ›

Amino groups can pick up hydrogen ions from the surroundings, so they make molecules basic. Other functional groups include sulfhydryl, carbonyl, methyl, and phosphate groups.

As a rule of thumb, the higher the oxidation state of the central carbon, the higher the priority of the functional group. Thus, carboxylic acids have higher priority than alcohols, and so on (See also table 21-1 in your textbook). 1. CARBOXYLIC ACIDS (highest priority among carbon-containing functional groups).

Among the functional groups hydroxyl, methyl, carbonyl, carboxyl, amino, phosphate, and sulfhydryl, the carboxyl group is most likely to gain a proton and become positively charged. This group generates acidity by releasing hydrogen ions (H+).

The surface hydroxyl groups of kaolinite can be protonated and deprotonated, which have an effect on the adsorption of rare earth elements (REEs).

Hydroxyl groups are simple structures consisting of an oxygen atom with two lone pairs bonded to a hydrogen atom. They readily participate in hydrogen bonding, generating either a net positively or negatively charged ion.

Answer and Explanation: A compound that is capable to donate a proton is known as an acid. Carboxylic acid is more capable to donate a proton (act as an acid) than alcohol due to the formation of a stable conjugate base.

Many of the groups are polar. These include hydroxyl, carboxyl, amine, aldehyde, and ketone groups. There are other mainly non-polar functional groups such as aromatic compounds, alkanes, and alkenes.

Functional groups containing oxygen atoms: carbonyl group C=O, alcohol R-OH, and ether R-O-R. The lone pair electrons on O in these groups are able to accept the protons, so functional groups like aldehyde, ketone, alcohol and ether are all organic bases.

As proton donors, carboxylic acids are characterized as Brønsted-Lowry acids. Acids with two or more carboxylic groups are called dicarboxylic, tricarboxylic, etc. Salts and esters of carboxylic acids are called carboxylates.
