Simonellite

Simonellite is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Simonellite rather than just read about it. In short: Simonellite (1,1-dimethyl-1,2,3,4-tetrahydro-7-isopropyl phenanthrene) is a polycyclic aromatic hydrocarbon with a chemical formula C19H24. It is similar to retene.

Key takeaways

Simonellite belongs to chemistry; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Simonellite to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Simonellite from memory before moving on to harder problems.

Reference excerpt

Simonellite (1,1-dimethyl-1,2,3,4-tetrahydro-7-isopropyl phenanthrene) is a polycyclic aromatic hydrocarbon with a chemical formula C19H24. It is similar to retene. Simonellite occurs naturally as an organic mineral derived from diterpenes present in conifer resins. It is named after its discoverer, Vittorio Simonelli (1860–1929), an Italian geologist. It forms colorless to white orthorhombic crystals. It occurs in Fognano, Tuscany, Italy. Simonellite, together with cadalene, retene and ip-iHMN, is a biomarker of higher plants, which makes it useful for paleobotanic analysis of rock sediments.

Worked examples

Example 1 — a first encounter with Simonellite

Start with the simplest possible case. Write down what Simonellite claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Simonellite before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Simonellite ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Simonellite

In research: Simonellite appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Simonellite in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Simonellite is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biomarkers, Diterpenes, Isopropyl compounds, so understanding it makes those chapters shorter.
In everyday life: Look for Simonellite outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Simonellite in simple terms?

Simonellite (1,1-dimethyl-1,2,3,4-tetrahydro-7-isopropyl phenanthrene) is a polycyclic aromatic hydrocarbon with a chemical formula C19H24. It is similar to retene.

Why does Simonellite matter?

Because it connects several chemistry ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Simonellite?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
