The molecular formula of chloride ofEka aluminium and Eka silicon respectively are

Options

A. `GaCl_3 and SICl_41`
B. `GaCl_3and AlcL_3`
C. `AlCl_3and SiCl_4`
D. `GaCl_3 and GeCl_4`

Answer

To find the molecular formulas of the chlorides of Eka-Aluminium and Eka-Silicon, we need to identify these elements and their respective valencies.

### Step 1: Identify Eka-Aluminium and Eka-Silicon
- **Eka-Aluminium** corresponds to **Gallium (Ga)**.
- **Eka-Silicon** corresponds to **Germanium (Ge)**.

### Step 2: Determine the Valency of Each Element
- **Gallium (Ga)** is in Group 13 of the periodic table, and its valency is **3**.
- **Germanium (Ge)** is in Group 14 of the periodic table, and its valency is **4**.

### Step 3: Determine the Valency of Chlorine
- The valency of **Chlorine (Cl)** is **1**.

### Step 4: Write the Molecular Formula for Gallium Chloride
- For Gallium (Ga) with a valency of 3 and Chlorine (Cl) with a valency of 1, we use the crisscross method:
- The formula will be **GaCl₃** (since we take 3 from Ga and 1 from Cl).

### Step 5: Write the Molecular Formula for Germanium Chloride
- For Germanium (Ge) with a valency of 4 and Chlorine (Cl) with a valency of 1, we again use the crisscross method:
- The formula will be **GeCl₄** (since we take 4 from Ge and 1 from Cl).

### Final Answer
The molecular formulas of the chlorides of Eka-Aluminium and Eka-Silicon are:
- **Gallium Chloride**: GaCl₃
- **Germanium Chloride**: GeCl₄

### Summary
- The molecular formula of the chloride of Eka-Aluminium (Gallium) is **GaCl₃**.
- The molecular formula of the chloride of Eka-Silicon (Germanium) is **GeCl₄**.
