Question

Answer

1)Molecular compound r made up of molecule nd no ions r present Thus, molecules r held together by weak covalent bond. 2)Molecules compound r insoluble in water but soluble in organic solvent.                                                               WHILE~                                    1) lonic compound r made up of Ionic ( cation & anion) held together by strong Ionic bonds. Thus, they have high melting nd boiling point.               2) lonic compound r soluble in water but insoluble in Organic solvent.:::::                         Thanksgiving

Answer

Ionic compounds are made of ionic bonds where the atoms are electrostatically attracted towards each other.This occur through the interaction between cations and anions.Molecular compounds are made of covalent bonds where the electrons are shared between the atoms involved in the formation. This occur through the interaction of neutral atoms.

Answer

Differences between Molecular and Ionic Compounds

Molecular and ionic compounds are two types of chemical compounds that have distinct properties and characteristics. Here, we will discuss the key differences between these two types of compounds.

Molecular Compounds

Molecular compounds are formed when atoms of different elements share electrons to form covalent bonds. These compounds consist of discrete molecules held together by relatively weak intermolecular forces. Key characteristics of molecular compounds include:

1. Bonding
- Molecular compounds are formed by the sharing of electrons between atoms through covalent bonds.
- Covalent bonds are formed between nonmetals or between a nonmetal and a metalloid.

2. Structure
- Molecular compounds have a definite molecular structure, where atoms are arranged in a specific pattern.
- The arrangement of atoms in a molecule is determined by the types and number of atoms involved in the compound.

3. State
- Molecular compounds generally exist as gases, liquids, or low-melting-point solids at room temperature.
- The weak intermolecular forces between molecules result in lower boiling and melting points compared to ionic compounds.

4. Electrical Conductivity
- Molecular compounds do not conduct electricity in their solid or liquid state.
- This is because molecules do not have free ions or charged particles that can carry an electric current.

Ionic Compounds

Ionic compounds are formed by the transfer of electrons between atoms, resulting in the formation of positive and negative ions. These compounds are composed of a lattice structure held together by strong electrostatic forces. Key characteristics of ionic compounds include:

1. Bonding
- Ionic compounds are formed by the transfer of electrons from a metal to a nonmetal.
- The transfer of electrons creates ions with opposite charges, which are held together by electrostatic attractions.

2. Structure
- Ionic compounds have a crystalline structure, with a repeating pattern of positive and negative ions in a three-dimensional lattice.
- The arrangement of ions in an ionic compound is determined by the ratio of cations to anions.

3. State
- Ionic compounds are typically solids at room temperature.
- The strong electrostatic forces between ions result in high melting and boiling points.

4. Electrical Conductivity
- Ionic compounds conduct electricity when dissolved in water or in molten form.
- In these states, the ions are free to move and carry an electric current.

In summary, the key differences between molecular and ionic compounds lie in their bonding, structure, state, and electrical conductivity. Molecular compounds involve the sharing of electrons and have a definite molecular structure, while ionic compounds involve the transfer of electrons and have a crystal lattice structure. Molecular compounds tend to be gases, liquids, or low-melting-point solids, while ionic compounds are typically solid at room temperature. Additionally, molecular compounds do not conduct electricity, whereas ionic compounds can conduct electricity when dissolved in water or in molten form.
