Options

A. `1sigma,1pi`
B. `1sigma,2pi`
C. `1sigma,5pi`
D. `1sigma`

Explanation

To determine the number and type of bonds between the two carbon atoms in SrC₂, we can follow these steps:

### Step 1: Identify the bonding in SrC₂
In the compound SrC₂, strontium (Sr) is a metal that typically forms a +2 oxidation state. The carbon atoms in C₂ are in the form of a carbide, where they are likely to be bonded together.

**Hint:** Consider the oxidation states of the elements involved and how they influence bonding.

### Step 2: Determine the bonding between carbon atoms
The two carbon atoms in C₂ are bonded together through a triple bond. A triple bond consists of one sigma bond and two pi bonds.

**Hint:** Recall that a triple bond is formed by the overlap of orbitals and consists of different types of bonds.

### Step 3: Analyze the types of bonds
- **Sigma bond (σ)**: This bond is formed by the head-on overlap of orbitals. In the case of carbon, this typically involves the overlap of sp hybridized orbitals.
- **Pi bonds (π)**: These bonds are formed by the side-to-side overlap of p orbitals. In a triple bond, there are two pi bonds formed.

**Hint:** Remember the distinction between sigma and pi bonds in terms of orbital overlap.

### Step 4: Conclusion
Therefore, between the two carbon atoms in SrC₂, there is one sigma bond and two pi bonds, resulting in a triple bond.

**Final Answer:** The number and type of bonds between the two carbon atoms in SrC₂ are 1 sigma bond and 2 pi bonds.
