Canonical Gymnasium Chemistry: E-Phase Reaction Foundations Audit

Snapshot: 2026-05-11

Purpose:

  • review the largest broad-cluster residue found in the horizontal all-state Chemistry topic-gap audit
  • decide whether broad source mappings to the canonical E-phase reaction-foundations packages expose missing atomic Chemistry goals
  • keep source-backed state projections stable without inflating the canonical graph from curriculum package wording alone

Scope

In scope:

  • canonical package Einfuehrungsphase Reaktionsgrundlagen
  • cluster-target mappings below that package in all Chemistry mapping reviews
  • source goals mapped to:
  • Erdol und Erdgas - Brennstoffe
  • Einfuehrung organische Verbindungen

Out of scope:

  • direct edits to the canonical Chemistry graph
  • exact-remapping all broad source rows to atom leaves
  • state cutover decisions

Residue Shape

The E-phase reaction-foundations package has 442 broad cluster-target mapping edges.

Cluster target States Broad mapping edges Main source signal
Erdol und Erdgas - Brennstoffe 11 236 hydrocarbons, homologous series, crude oil / natural gas, cracking, combustion, fuel comparison, raw-material and sustainability evaluation
Einfuehrung organische Verbindungen 11 206 organic/anorganic distinction, homologous series, IUPAC / isomerism, oxygen-containing functional groups, ester formation, structure-property relations

The broad rows are concentrated in newer large source extractions, especially DE-SL, DE-SN, DE-ST, DE-RP, DE-TH, and DE-MV. Older compact lanes such as DE-HB, DE-HH, and DE-NI mostly confirm the same surface with fewer rows.

Source Evidence

Erdol / Erdgas / Brennstoffe

Representative evidence:

  • fossil energy-carrier origin and processing
  • crude oil / natural gas as mixtures of hydrocarbons and raw materials for chemical industry
  • alkane / alkene / alkyne structure, homologous series, formulae, isomerism, and basic reactions
  • fractional distillation, cracking, combustion, substitution, addition, and bromine evidence for multiple bonds
  • ecological, economic, and ethical evaluation of fossil and renewable energy carriers
  • use of researched thermodynamic data for fuel and energy-source evaluation

Judgment:

  • this is a genuine shared package surface
  • the current canonical atoms already cover the key assessable routines
  • broad source rows often combine structure, process, use, and evaluation in one official line, so forcing one atom per line would overfit source wording

Einfuehrung organische Verbindungen

Representative evidence:

  • organic / inorganic distinction and relevance of organic compounds
  • alkanes, alkenes, alkynes, alcohols, aldehydes, ketones, carboxylic acids, esters, amines, and selected biomolecular continuations
  • homologous series, molecular formulae, structural formulae, IUPAC naming, and isomerism
  • structure-property relations through polarity, intermolecular forces, solubility, and boiling behavior
  • functional-group recognition and selected qualitative evidence
  • ester formation, hydrolysis, and simple reaction-mechanism references

Judgment:

  • this is also a stable shared package surface
  • source rows vary strongly in granularity: some are Sek-I organic introductions, others are upper-secondary organic reaction-pathway summaries
  • no single missing atomic goal appears across states that is not already represented by the current organic / functional-group / reaction-pathway atoms elsewhere in the canonical Chemistry spine

Boundary Decisions

  1. Keep Erdol und Erdgas - Brennstoffe as a learner-visible package surface.
  2. Keep Einfuehrung organische Verbindungen as a learner-visible package surface.
  3. Treat broad source mappings here as accepted package evidence, not source-coverage debt.
  4. Do not add new canonical atoms in this pass.
  5. Do not broaden state applicability merely because a source row mentions a package label.
  6. Reopen only if a later exact-remapping pass finds repeated source statements for a missing assessable routine, not just repeated package wording.

Follow-Up

The next horizontal Chemistry review lane is Energie und Nachhaltigkeit, because it has the next largest all-state broad-cluster signal and mixes energy, thermodynamics, sustainability, and applied evaluation more strongly than the organic introduction surface.
