The bond between two carbons in alkane is

Options

A. `180^(@)`
B. `120^(@)`
C. `109^(@)`
D. `90^(@)`

Explanation

To determine the bond angle between two carbon atoms in alkanes, we can follow these steps:

### Step 1: Understand the Structure of Alkanes
Alkanes are saturated hydrocarbons, which means they contain only single bonds between carbon atoms. The general formula for alkanes is CnH2n+2.

### Step 2: Identify the Hybridization of Carbon in Alkanes
In alkanes, each carbon atom is sp³ hybridized. This means that one s orbital and three p orbitals mix to form four equivalent sp³ hybrid orbitals.

### Step 3: Determine the Geometry of sp³ Hybridization
The geometry associated with sp³ hybridization is tetrahedral. In a tetrahedral arrangement, the bond angles between the bonds are approximately 109.5 degrees.

### Step 4: Conclusion
Since the bond angle between two carbon atoms in alkanes is determined by their sp³ hybridization, the bond angle is approximately 109 degrees.

### Final Answer
The bond between two carbons in alkane is approximately 109 degrees.
