Nikolai Prilezhaev

Nikolai Prilezhaev 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 Nikolai Prilezhaev rather than just read about it. In short: Nikolai Alexandrovich Prilezhaev, Russian: Николай Александрович Прилежаев, (Born September 15 [O.S. 27], 1887 in Kopossevo near Nizhny Novgorod, died May 26, 1944, in Moscow) was a Russian organic chemist. The Prilezhaev reaction, in which an alkene and a peroxyacid react to form an epoxide, is named after him.

Key takeaways

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

Reference excerpt

Nikolai Alexandrovich Prilezhaev, Russian: Николай Александрович Прилежаев, (Born September 15 [O.S. 27], 1887 in Kopossevo near Nizhny Novgorod, died May 26, 1944, in Moscow) was a Russian organic chemist. The Prilezhaev reaction, in which an alkene and a peroxyacid react to form an epoxide, is named after him. Prilezhaev was the son of a clergyman and studied chemistry at the Theological Seminary in Warsaw (graduated in 1895) and then at the University of Warsaw under the supervision of Yegor Yegorovich Vagner (Georg Wagner). After graduating in 1900 he was assistant professor of organic chemistry at the Polytechnic in Warsaw where he belonged to the school of organic chemistry founded by Wagner. After earning a master's degree in 1912 in St. Petersburg, he became an associate professor of organic chemistry at the University of Warsaw. In 1915 he became a professor at the Polytechnic in Kiev and 1924 at the University of Minsk. There he established the Faculty of Chemistry and between 1931 and 1933 was director of the Institute of Chemistry of the Belarusian Academy of Sciences. He dealt mostly with oxidation processes, following in the footsteps of chemists such as Alexei Nikolaevich Bach. For example, he studied reactions between unsaturated compounds and peroxides. He discovered his name reaction in 1908 and continued to study its intermediates and products. He was a corresponding member of the Soviet Academy of Sciences (1933) and a member of the Belarusian Academy of Sciences (1940). In 1912 he received the Butlerov Prize.

Worked examples

Example 1 — a first encounter with Nikolai Prilezhaev

Start with the simplest possible case. Write down what Nikolai Prilezhaev 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 Nikolai Prilezhaev 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 Nikolai Prilezhaev 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 Nikolai Prilezhaev

In research: Nikolai Prilezhaev 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 Nikolai Prilezhaev 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: Nikolai Prilezhaev is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1877 births, 1944 deaths, 19th-century chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Nikolai Prilezhaev 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.
