Answer:
The structures are shown below.
Step-by-step explanation:
The conjugate base of an acid is the base that is formed when the acid lost a proton (H⁺) in a solution. For a generic acid, HA, the conjugate base is A⁻.
The pyrrole is a base that has a ring with 4 carbons and 1 nitrogen and double bonds between carbons 1 and 2 and between carbons 3 and 4. The nitrogen is between carbons 1 and 4 and has a bond with a hydrogen. When it dissociates, it can lose the hydrogen, and form the conjugate base, which is shown in the picture below. Nitrogen has 5 valence electrons, and in the conjugate base it will do 2 bonds, so it will have 2 lone pairs and 1 free electron.
The cyclopentadiene is formed by a ring of 5 carbons and has double bonds between carbons 1 and 2, and between carbons 3 and 4. When in solution, one of the hydrogens attached in carbons with double bonds will be lost (because it's the more acidic hydrogen, and the structure will be more stable because of the double bond!), so the conjugate base structure is shown below.
