The 58 pages that link to Methane, each with the reason it gives.

• Greenhouse gas emissionsBroader topic: It is a potent greenhouse gas released by energy, agriculture, waste, and natural sources.

• Tetrahedral molecular geometryBroader topic: Its four equivalent C–H bonds form the textbook tetrahedral shape.

• Global warming potentialBroader topic: Its high near-term GWP makes methane emissions consequential in short-horizon comparisons.

• Valence bond theoryBroader topic: Its tetrahedral bonds are commonly described using carbon hybrid orbitals.

• Liquefied natural gasBroader topic: Methane makes up most LNG and determines its principal combustion and storage properties.

• Greenhouse gasBroader topic: Its strong near-term warming effect contrasts with its shorter atmospheric lifetime than carbon dioxide.

• Atmospheric lifetimeBroader topic: Its finite lifetime makes methane emissions responsive to changes in atmospheric chemistry and emissions.

• MoleculeBroader topic: Its tetrahedral shape demonstrates how four bonds arrange around a central atom.

• Bond angleBroader topic: Its H–C–H angles are close to the tetrahedral value of 109.5°.

• VSEPR theoryBroader topic: Four equivalent bonding domains give methane its tetrahedral shape.

• Hybrid orbitalBroader topic: Its four equivalent C–H bonds are classically described using carbon sp3 hybrids.

• Air–sea gas exchangeBroader topic: Marine methane release can transfer this greenhouse gas from ocean to atmosphere.

• Rotational–vibrational spectroscopyBroader topic: Its symmetry and multiple vibrational modes produce characteristic infrared band patterns.

• Orbital hybridisationBroader topic: Its equivalent bonds are classically described using four carbon sp3 hybrids.

• Trouton's ruleBroader topic: Its small, non-associating molecules provide a contrasting case for entropy estimates.
