Harold C Urey was awarded the Nobel Prize in Chemistry, in 1934:
1934 में, हेरोल्ड सी. उरे को रसायन विज्ञान में नोबेल पुरस्कार किस कारण से सम्मानित किया गया था?
Detailed Solution & Logic
for the discovery of heavy hydrogen/ भारी हाइड्रोजन की खोज के लिए
📘 Explanation
American chemist Harold C. Urey was awarded the Nobel Prize in Chemistry in 1934 for the discovery of heavy hydrogen, also known as deuterium.
Deuterium is an isotope of hydrogen that contains one proton and one neutron, making it heavier than ordinary hydrogen.
अमेरिकी रसायनज्ञ Harold C. Urey को 1934 में रसायन विज्ञान का नोबेल पुरस्कार भारी हाइड्रोजन (ड्यूटेरियम) की खोज के लिए दिया गया था।
ड्यूटेरियम हाइड्रोजन का एक समस्थानिक है, जिसमें एक प्रोटॉन और एक न्यूट्रॉन होता है, इसलिए यह सामान्य हाइड्रोजन से भारी होता है।
📌 Extra Facts
1. Deuterium Symbol / प्रतीक:
- Symbol is D or ²H.
- इसका प्रतीक D या ²H होता है।
2. Heavy Water / भारी पानी:
- Deuterium is used to make heavy water (D₂O), important in nuclear reactors.
- ड्यूटेरियम से भारी पानी (D₂O) बनता है, जो परमाणु रिएक्टर में उपयोगी है।
3. Nobel Category / नोबेल क्षेत्र:
- Awarded in Chemistry (1934).
- यह पुरस्कार रसायन विज्ञान (1934) में दिया गया।
4. Other Contributions / अन्य योगदान:
- Urey also contributed to studies on the origin of life and planetary science.
- उरे ने जीवन की उत्पत्ति और ग्रह विज्ञान पर भी महत्वपूर्ण कार्य किया।
❌ Why Other Options Are Wrong
- Transuranium elements: Discovered later by other scientists
- Conductive polymers: Nobel Prize 2000
- Density-functional theory: Developed much later
