NaCl has -

Options

A. covalent bond
B. ionic bond
C. co-ordinate bond
D. none

Answer

To analyze the question "NaCl has -", we need to determine the type of bond present in sodium chloride (NaCl) and its properties. Here’s a step-by-step breakdown of the solution:

### Step 1: Identify the Components of NaCl
NaCl is composed of sodium (Na) and chlorine (Cl). Sodium is a metal, and chlorine is a non-metal.

**Hint:** Remember that metals tend to lose electrons while non-metals tend to gain electrons.

### Step 2: Determine the Type of Bond
Sodium (Na) has one electron in its outermost shell and tends to lose that electron to achieve a stable electron configuration. Chlorine (Cl), on the other hand, has seven electrons in its outer shell and tends to gain one electron to complete its octet. When Na loses an electron, it becomes Na⁺, and when Cl gains an electron, it becomes Cl⁻.

**Hint:** Think about how the transfer of electrons between a metal and a non-metal leads to the formation of ions.

### Step 3: Formation of Ionic Bond
The electrostatic attraction between the positively charged sodium ion (Na⁺) and the negatively charged chloride ion (Cl⁻) results in the formation of an ionic bond. This bond is characterized by the transfer of electrons from one atom to another.

**Hint:** Ionic bonds are typically formed between metals and non-metals due to the transfer of electrons.

### Step 4: Properties of NaCl
NaCl, being an ionic compound, has distinct properties:
- It has a high melting and boiling point due to the strong ionic bonds.
- It is soluble in water.
- It conducts electricity when dissolved in water or molten because the ions are free to move.

**Hint:** Consider how the structure of ionic compounds affects their physical properties.

### Final Answer
NaCl has an ionic bond formed between sodium (Na) and chlorine (Cl) due to the transfer of electrons from Na to Cl, resulting in the formation of Na⁺ and Cl⁻ ions.
