Phenanthrenequinone

Phenanthrenequinone 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 Phenanthrenequinone rather than just read about it. In short: Phenanthrenedione is a quinone derivative of a polycyclic aromatic hydrocarbon. It is an orange, water-insoluble solid.

Key takeaways

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

Reference excerpt

Phenanthrenedione is a quinone derivative of a polycyclic aromatic hydrocarbon. It is an orange, water-insoluble solid.

Laboratory synthesis and use It has been prepared by oxidation of phenanthrene with chromic acid. It is used as an artificial mediator for electron acceptor/donor in Mo/W containing formate dehydrogenase reduction of carbon dioxide to formate and vice versa. It is a better electron acceptor than the natural nicotinamide adenine dinucleotide (NAD+).

Safety It is cytotoxic and potentially mutagenic. Phenanthrenequinone is one of many contributors to harmful particulate emissions from diesel motor vehicles.

Worked examples

Example 1 — a first encounter with Phenanthrenequinone

Start with the simplest possible case. Write down what Phenanthrenequinone 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 Phenanthrenequinone 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 Phenanthrenequinone 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 Phenanthrenequinone

In research: Phenanthrenequinone 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 Phenanthrenequinone 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: Phenanthrenequinone is common in secondary-school and first-year university syllabi. It links to neighbouring topics Organic compound stubs, Phenanthrenes, Quinones, so understanding it makes those chapters shorter.
In everyday life: Look for Phenanthrenequinone 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.
