Question
The image presents a question about identifying the correct Lewis structure for hydrogen cyanide, which consists of three atoms: hydrogen, carbon, and nitrogen. Below the question, multiple choice options are provided with different Lewis structures:

1. **Option 1:**
   - H with a triple bond to N, which is triple bonded to C 
   - Nitrogen has two lone pairs of electrons.

2. **Option 2:**
   - H single bonded to N, which is single bonded to C 
   - Both N and C have three lone pairs of electrons.

3. **Option 3:**
   - H single bonded to C, which is triple bonded to N 
   - Nitrogen has one lone pair of electrons.

4. **Option 4:**
   - H single bonded to N, which is triple bonded to C 
   - Carbon has one lone pair of electrons.

5. **Option 5:**
   - H with a triple bond to C, which is triple bonded to N 
   - Carbon has two lone pairs of electrons.

6. **Option 6:**
   - H single bonded to C, which is single bonded to N 
   - C and N both have three lone pairs of electrons.

These diagrams aim to represent the possible electron pair distributions around the atoms in hydrogen cyanide (HCN).
