**Question:**

How many sigma and pi bonds are in the molecule shown below?

**Molecule Structure:**

H–C≡N:

**Answer Options:**

- Sigma bonds: [Select]
- Pi bonds: [Select]

**Explanation:**

The molecule depicted is hydrogen cyanide (HCN). The structure shows a single bond between hydrogen (H) and carbon (C), and a triple bond between carbon (C) and nitrogen (N). 

In covalent bonding:
- **Sigma (σ) bonds**: The first bond formed between two atoms. In HCN, there are two sigma bonds; one in the H-C bond and one in the C-N bond.
- **Pi (π) bonds**: Additional bonds formed in multiple bonding situations. The C-N triple bond consists of one sigma bond and two pi bonds.

Therefore:
- Total sigma bonds: 2
- Total pi bonds: 2
