Moti Lal Dhar

Moti Lal Dhar 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 Moti Lal Dhar rather than just read about it. In short: Moti Lal Dhar (22 October 1914 – 20 January 2002) was an Indian chemist and academic administrator. He was director of the Central Drug Research Institute (CDRI), Lucknow, from 1962 until his retirement in 1972 to serve as vice-chancellor of Banaras Hindu University.

Key takeaways

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

Reference excerpt

Moti Lal Dhar (22 October 1914 – 20 January 2002) was an Indian chemist and academic administrator. He was director of the Central Drug Research Institute (CDRI), Lucknow, from 1962 until his retirement in 1972 to serve as vice-chancellor of Banaras Hindu University.

Early life and education Moti Lal Dhar was born on 22 October 1914 at Srinagar, Kashmir. He earned his MSc degree from Punjab University, and continued his studies in the United Kingdom on a scholarship from the Jammu and Kashmir State Government. After obtaining a PhD from the University of London in 1940, he returned to India. In the late 1950s, he was also a visiting scientist in the laboratory of Linus Pauling at the California Institute of Technology.

Professional career After his return to India in 1940, he joined the Drug Research Laboratory at Jammu, where he worked for approximately ten years as a chemist. In 1950, he joined the newly established Central Drug Research Institute (CDRI) at Lucknow as a scientific officer. In 1962, he was appointed the director of the institute. He retired from CDRI in 1974, after having worked there for 24 years, of which he was the director for the last twelve. After his retirement, he was appointed the Chairman of the Board of Governors of the Indian Institute of Technology, Kanpur (1974–1976). Later, he served as the vice-chancellor of Banaras Hindu University.

Worked examples

Example 1 — a first encounter with Moti Lal Dhar

Start with the simplest possible case. Write down what Moti Lal Dhar 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 Moti Lal Dhar 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 Moti Lal Dhar 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 Moti Lal Dhar

In research: Moti Lal Dhar 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 Moti Lal Dhar 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: Moti Lal Dhar is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 births, 2002 deaths, 20th-century Indian chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Moti Lal Dhar 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.
