Draw the resonance contributors for the species/molecules shown in the boxes below. Then, indicate which species (if any) is the MAJOR contributor towards the resonance hybrid (most stable).

**1. Resonance Practice!**

**Instructions:** Draw the resonance contributors for the species/molecules shown in the boxes below. Then, indicate which species (if any) is the MAJOR contributor towards the resonance hybrid (most stable).

---

**a.**

Structure: A molecule with a positively charged oxygen atom at one end, connected to a sequence of single and double bonds extending through a carbon chain.

Boxes: Three empty boxes are provided to draw resonance structures with double-headed arrows between them.

---

**b.**

Structure: A molecule showing an amide group (O=C-NH) adjacent to an alkene group.

Boxes: Two empty boxes are provided with a double-headed arrow between them for drawing resonance structures.

---

**c.**

Structure: A cyclic molecule with an oxygen atom double-bonded to a carbon atom, displaying a negative charge on an oxygen atom outside the ring.

Boxes: Three empty boxes are provided with double-headed arrows between them to illustrate possible resonance structures.

---

Fill in the boxes with resonance forms, and identify the most stable (major) contributor among them.
