Vsevolod Perekalin 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 Vsevolod Perekalin rather than just read about it. In short: Vsevolod Vasilyevich Perekalin (Russian: Всеволод Васильевич Перекалин; 27 February 1913, Saint Petersburg – 7 January 1998, Saint Petersburg) was a Soviet and Russian organic chemist, Doktor nauk. He created the drug known as Phenibut.

Reference excerpt

Vsevolod Vasilyevich Perekalin (Russian: Всеволод Васильевич Перекалин; 27 February 1913, Saint Petersburg – 7 January 1998, Saint Petersburg) was a Soviet and Russian organic chemist, Doktor nauk. He created the drug known as Phenibut.

Biography His father was a military physician. He was a student of Academician Alexander Jewgenjewitsch Porai-Koschiz. In 1940, he defended his Candidate's Dissertation at the N.D. Zelinsky Institute of Organic Chemistry. In 1949, he defended his doctoral dissertation. From 1950 to 1992, Perekalin headed the Department of Organic Chemistry at the Herzen University. In this University he organized the Faculty of Chemistry. He taught in the Herzen University for 48 years. In 1995, he was appointed Soros Professor. He has a son Pyotr. Perekalin is the author of more than 350 scientific papers.

Worked examples

Example 1 — a first encounter with Vsevolod Perekalin

Start with the simplest possible case. Write down what Vsevolod Perekalin 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 Vsevolod Perekalin 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 Vsevolod Perekalin 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 Vsevolod Perekalin

In research: Vsevolod Perekalin 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 Vsevolod Perekalin 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: Vsevolod Perekalin is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1913 births, 1998 deaths, Recipients of the Order of the Red Banner of Labour, so understanding it makes those chapters shorter.
In everyday life: Look for Vsevolod Perekalin 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.
