Kennedy J. P. Orton

Kennedy J. P. Orton 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 Kennedy J. P. Orton rather than just read about it. In short: Kennedy Joseph Previté-Orton (21 January 1872 – 16 March 1930) was a British chemist who became a lecturer and demonstrator at St Bartholomew's Hospital and then became a professor at Bangor. He was also a keen climber, amateur geologist, ornithologist and bird conservationist.

Reference excerpt

Kennedy Joseph Previté-Orton (21 January 1872 – 16 March 1930) was a British chemist who became a lecturer and demonstrator at St Bartholomew's Hospital and then became a professor at Bangor. He was also a keen climber, amateur geologist, ornithologist and bird conservationist.

Life and work Kennedy Orton was born in St. Leonard's on Sea to clergyman William Previté and Eliza Orton. His grandfather was Italian and the name Previte is a Sicilian form of Prete. Kennedy's father studied at St. John's College Cambridge and was thirty-first wrangler in 1860, becoming a vicar in Leicester. After marrying he took the surname of his wife. Kennedy was the eldest son. He studied at Kibworth Grammar School (1882–1885) and then Wyggeston School, Leicester (1885–1888) before pursuing medicine at St. Thomas' Hospital, but there he became interested in chemistry and moved to St. John's College, Cambridge. He then obtained a Ph.D. summa cum laude in Heidelberg under Karl von Auwers, before working for a year with Sir William Ramsey at University College, London. He was then lecturer and demonstrator of Chemistry at St. Bartholomew's Hospital, working under F. D. Chattaway (1860–1944) who would inspire much of his subsequent research. He would examine N-halogen compounds, reaction mechanisms and equilibria. In 1903 he was appointed Professor of Chemistry at University College of North Wales, Bangor, where he headed the department until his death. After World War I, his department in Bangor became a centre for research in physical organic chemistry. He collaborated with Chattaway on the synthesis and study of nitro-halogen compounds. He worked on reaction mechanisms and kinetics in collaboration with Arthur Lapworth which led to his breaking away from Chattaway. He was elected a Fellow of the Royal Society in 1921. His collaborators and students included Herbert Ben Watson (1894–1975), Alan Edwin Bradfield (1897–1953), Edward David Hughes (1906–1963), Brynmor Jones (1903–1989), Gwyn Williams (1904–1955), and Frederick George Soper (1898–1982). Besides being a chemist, he was a keen climber, geologist, and ornithologist, and a biannual ornithological lecture was endowed in his name. He married Annie Ley in 1897 and they had a son and two daughters. He died from pneumonia.

Worked examples

Example 1 — a first encounter with Kennedy J. P. Orton

Start with the simplest possible case. Write down what Kennedy J. P. Orton 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 Kennedy J. P. Orton 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 Kennedy J. P. Orton 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 Kennedy J. P. Orton

In research: Kennedy J. P. Orton 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 Kennedy J. P. Orton 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: Kennedy J. P. Orton is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1872 births, 1930 deaths, Alumni of St John's College, Cambridge, so understanding it makes those chapters shorter.
In everyday life: Look for Kennedy J. P. Orton 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.
