What chemical property is given to a biomolecule with a hydroxyl (--oh) functional group?

1 answer:

3 0

A biomolecule with a hydroxyl (--oh) functional group is given the polar chemical property since organic molecules with an OH group are polar.

A part of a larger molecule is made up by a functional group. The hydroxyl group (-OH) that characterizes alcohols, an oxygen with a hydrogen attached, is an example of it. This group can be found on any number of different molecules.

Functional groups have characteristic chemistries, just as elements have unique properties., although perhaps not identically, to an -OH on another molecule. Although perhaps not identically to an -OH on another molecule, an -OH group on one molecule will tend to react similarly.

In each equation, label the acids, bases, and conjugate acid-base pairs. (Type your answer using the format [NO3]- for NO3-.)

Kamila [148]

Answer:

a) O²⁻ + H₂O <-----> OH⁻ + OH⁻

Acid = H₂O

Base = O²⁻

Conjugate Acid = OH⁻

Conjugate Base = OH⁻

b) HClO₄ + H₂SO₄ <-----> ClO₄⁻ + H₃SO₄⁺

Acid = HClO₄

Base = H₂SO₄

Conjugate Acid = H₃SO₄⁺

Conjugate Base = ClO₄⁻

c) NH₃ + HNO₃ <--> NH4⁺ + NO₃⁻

Acid = HNO₃

Base = NH₃

Conjugate Acid = NH4⁺

Conjugate Base = NO₃⁻

Explanation:

- Acids are molecules or ions capable of donating a proton (H⁺).

- Bases are molecules or ions that readily accept the H⁺ from acids.

- Conjugate Acids, according to the Brønsted–Lowry acid–base theory, are chemical compounds formed after the reception of a proton (H⁺) from an acid by a base.

- Conjugate Bases, Brønsted–Lowry acid–base theory, are the leftovers from when acids donate their proton (H⁺).

When atomic orbitals of two nuclei overlap, the mutual attraction between a negatively charged electron pair and the two positiv

Lera25 [3.4K]

Answer: Option (A) is the correct answer.

Explanation:

It is known that when sharing of electrons take place between two combining atoms then the bond formed is known as a covalent bond. In general, a covalent bond is formed between two non-metal atoms.

For example, the compound HCl has a covalent bond between the hydrogen and chlorine atom. As hydrogen atom has 1 valence electron and chlorine atom has 7 valence electrons.

So, in order to attain stability both these atoms will share their valence electrons and hence, a covalent bond is formed.

On the other hand, when an electron is transferred from one atom to another then it tends to form an ionic bond.

For example, the compound NaCl has an ionic bond.

Thus, we can conclude that when atomic orbitals of two nuclei overlap, the mutual attraction between a negatively charged electron pair and the two positively charged nuclei forms a covalent bond.
