Maximum number of bonds in

Options

A. `CO_(2)`
B. `H_(2)`O
C. `H_(2)`S
D. All have same number of bonds because all are triatomic molecule

Answer

To determine which molecule among CO2, H2O, and H2S has the maximum number of bonds, we will analyze the bonding in each of these compounds step by step.

### Step 1: Analyze the structure of CO2 (Carbon Dioxide)
- CO2 has a linear structure.
- The carbon atom is double bonded to each of the two oxygen atoms.
- The structure can be represented as O=C=O.
- Counting the bonds:
- There are 2 double bonds, which means 4 bonds in total (2 bonds per double bond).

**Hint for Step 1:** Remember that a double bond consists of 2 bonds, so count accordingly.

### Step 2: Analyze the structure of H2O (Water)
- H2O has a bent structure.
- The oxygen atom is bonded to two hydrogen atoms.
- The structure can be represented as H-O-H.
- Counting the bonds:
- There are 2 single bonds (one bond between each hydrogen and the oxygen).

**Hint for Step 2:** A single bond counts as one bond, so just count the number of single bonds.

### Step 3: Analyze the structure of H2S (Hydrogen Sulfide)
- H2S also has a bent structure similar to water.
- The sulfur atom is bonded to two hydrogen atoms.
- The structure can be represented as H-S-H.
- Counting the bonds:
- There are 2 single bonds (one bond between each hydrogen and the sulfur).

**Hint for Step 3:** Similar to water, count only the single bonds for H2S.

### Step 4: Compare the number of bonds in each molecule
- CO2 has a total of 4 bonds.
- H2O has a total of 2 bonds.
- H2S has a total of 2 bonds.

### Conclusion
- Among CO2, H2O, and H2S, CO2 has the maximum number of bonds, which is 4.
- Therefore, the answer is CO2.

**Final Answer:** CO2 has the maximum number of bonds (4), while H2O and H2S each have 2 bonds.
