Lai Yee Hing

Lai Yee Hing 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 Lai Yee Hing rather than just read about it. In short: Lai Yee Hing (Chinese: 賴怡興; pinyin: Lài Yíxìng) is a Singaporean organic chemistry professor based in the National University of Singapore. He was the principal of NUS High School of Mathematics and Science and held this position from July 2004 to 30 August 2007.

Key takeaways

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

Reference excerpt

Lai Yee Hing (Chinese: 賴怡興; pinyin: Lài Yíxìng) is a Singaporean organic chemistry professor based in the National University of Singapore. He was the principal of NUS High School of Mathematics and Science and held this position from July 2004 to 30 August 2007. Lai Yee Hing graduated with a BSc from the former Nanyang University (now National University of Singapore) in 1976 and received his PhD from the University of Victoria in 1980. Following that he spent 2 years in University of California Berkeley as a post-doctoral fellow, working with Peter Vollhardt. His research interests include novel aromatic compounds, conjugated organic materials and macrocycles.

Worked examples

Example 1 — a first encounter with Lai Yee Hing

Start with the simplest possible case. Write down what Lai Yee Hing 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 Lai Yee Hing 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 Lai Yee Hing 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 Lai Yee Hing

In research
Lai Yee Hing 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 Lai Yee Hing 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
Lai Yee Hing is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the National University of Singapore, Living people, Singaporean chemists, so understanding it makes those chapters shorter.
In everyday life
Look for Lai Yee Hing 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.
