PT1. Oxygen and sulfur have similar chemical properties due to having six valence electrons. Both form molecules with two hydrogen atoms. Surprisingly, water (H₂O) is a liquid, yet H₂S is a gas, even though sulfur is much larger and heavier than oxygen. Why? Explain fully.

PT2.

Both cyclopentadiene and cyclopentadienyl nion have same valence electrons and same 5-membered Carbon ring structure. However, cyclopentadiene adopts "envelope" shape with C on right tilted out of the plane of 4 Carbon atoms. The anion adopts flat structure. Further, the anion is far more stable chemically than cyclopentadiene. Speculate why this is so. Answer should consider both hybridization and resonance.
