Question

Скласти електронні та структурні формули запропонованих молекул, вказати тип ковалентного зв'язку, визначити валентність елементів в формулах: Cl2; H2S; CO2; O2; N2​

Answer 1

Ответ:

Електронні та структурні формули;

CI2: CI:CI, CI–CI

H2S: H:S:H, H→S←H

CO2: O:C:O, O→C←O

O2: O:O, O–O

N2: N:N, N–N

Тип ковалентного зв’язку:

Ковалентний неполярний зв'язок - CI2, O2,N2

Ковалентний полярний - H2S, CO2

Валентність елементів:

CI2 = I

H2S: H=I, S=II

CO2: C=IV, O=II

O2=II

N2=III

Molecular and Structural Formulas, Types of Covalent Bonds, and Valence of Elements

Here are the molecular and structural formulas, types of covalent bonds, and valence of elements for the given molecules:

1. Cl2: - Molecular Formula: Cl2 - Structural Formula: Cl-Cl - Type of Covalent Bond: Single bond - Valence of Elements: Chlorine (Cl) has a valence of 7, so each chlorine atom in Cl2 shares one electron with the other chlorine atom, forming a single covalent bond.

2. H2S: - Molecular Formula: H2S - Structural Formula: H-S-H - Type of Covalent Bond: Single bond - Valence of Elements: Hydrogen (H) has a valence of 1, and sulfur (S) has a valence of 2. Each hydrogen atom in H2S shares one electron with the sulfur atom, forming a single covalent bond.

3. CO2: - Molecular Formula: CO2 - Structural Formula: O=C=O - Type of Covalent Bond: Double bond - Valence of Elements: Carbon (C) has a valence of 4, and oxygen (O) has a valence of 2. The carbon atom in CO2 shares two electrons with each oxygen atom, forming two double covalent bonds.

4. O2: - Molecular Formula: O2 - Structural Formula: O=O - Type of Covalent Bond: Double bond - Valence of Elements: Oxygen (O) has a valence of 2. Each oxygen atom in O2 shares two electrons with the other oxygen atom, forming a double covalent bond.

5. N2: - Molecular Formula: N2 - Structural Formula: N≡N - Type of Covalent Bond: Triple bond - Valence of Elements: Nitrogen (N) has a valence of 3. Each nitrogen atom in N2 shares three electrons with the other nitrogen atom, forming a triple covalent bond.
