A more electronegative atom A) will have more attraction to the electrons in a chemical bond. B) is more likely to lose an elect
DIA [1.3K]

Answer: A more electronegative atom will have more attraction to the electrons in a chemical bond.

Explanation:

An atom that is able to attract electrons or shared pair of electrons more towards itself is called an electronegative atom.

For example, fluorine is the most electronegative atom.

Due to its high electronegativity it is able to attract an electropositive atom like H towards itself. As a result, both fluorine and hydrogen will acquire stability by sharing of electrons.

Thus, we can conclude that a more electronegative atom will have more attraction to the electrons in a chemical bond.

CH3CI, CF4, HCI, NH3 which would have the lowest boiling point
Sergio [31]

Boiling point of a compound is determined by the strength of intermolecular forces of attraction between the molecules present in it. Stronger the intermolecular forces of attraction, higher will be the boiling point.

Ionic compounds show ion-ion interactions which are the strongest among all. Ion-dipole interactions are shown when ionic solutes are dissolved in polar solvents. Hydrogen bonding is also a relatively stronger force that is present between H atom and an electronegative atom like F, O and N(NH_{3}) . All polar molecules show dipole-dipole interaction (CH_{3}Cland HCl). Dispersion forces are the weakest intermolecular forces due to momentary dipoles between electron clouds and nucleus.

Among the given compounds, CF_{4}has dispersion forces as the major intermolecular forces of attraction. So they they exhibit the weakest IMF, hence have the lowest boiling point.

A solution containing an equal number of hydrogen ions and hydroxide ions isA. basicB. alkalineC. acidicD. neutral.
Goryan [66]

Answer:

Neutral (Option D)

Explanation:

[H₃O⁺] = [OH⁻]  → Neutral solution   pH = 7

[H₃O⁺] < [OH⁻]  → Alkaline / Basic solution   pH > 7

[H₃O⁺] > [OH⁻] → Acidic solution   pH < 7

The four lines observed in the visible emission spectrum of hydrogen tell us that: a. We could observe more lines if we had a st
Aliun [14]

Answer:

c. Only certain energies are allowed for the electron in a hydrogen atom

Explanation:

Emission spectrum are produced when the excited electron in a atom release the energy in the form of photons to come to ground state. These photons are of different wavelengths depending on the excitation state of emitting electron or transition of electron. These electromagnetic radiation are observed through prism to produce the spectrum.

As the name indicates this spectrum is produced by emission of energy. Although the electron can be excited by different methods such as by heating but the key point is that electrons in hydrogen atom will emit the photons of same energy which they absorb and each electron can absorb only certain type of energy. So four lines were observed in the visible spectrum of hydrogen because only certain energies are observed for hydrogen atom.
