इंग्रजी मध्ये NUCLEOPHILICITY म्हणजे काय?
न्यूक्लओफाइल
न्युक्लिओफेइल एक रासायनिक प्रजाती आहे जी एका इलेक्ट्रॉन जोडीला इलेक्ट्रॉफिनीला एक प्रतिक्रिया देण्याशी संबंधित रासायनिक बंध तयार करण्यासाठी देणगी देते. एक मुक्त जोड्या किंवा कमीतकमी एक पाई बॉन्ड असलेल्या सर्व रेणू किंवा आयन न्युक्लेओफिल्सच्या रूपात कार्य करू शकतात. न्युक्लियोफिल्सने इलेक्ट्रॉनचा दान केल्यामुळे, त्यांची परिभाषा लेविसच्या बेसवर आहे न्यूक्लेओफिलिक न्यूक्लीओफाइलच्या केंद्रस्थानी असलेल्या नातेसंबंधांचे वर्णन करतात. Nucleophilicity, ज्याला कधीकधी न्यूक्लॉयीफिलाची शक्ती म्हणतात, एखाद्या पदार्थाच्या न्युक्लिओफिलिक वर्णास संदर्भित करते आणि अणूंचे आत्मीयता यांची तुलना सहसा वापरली जाते. अल्कोहोल आणि पाणी यासारख्या सॉल्व्हन्टससह न्यूट्रल न्यूक्लओओफिलिक प्रतिक्रियांना सॉल्व्होलिसीस असे म्हणतात. न्यूक्लियोफिल्स न्युक्लिओफिलिक प्रतिस्थापनामध्ये भाग घेऊ शकतात, ज्यामध्ये एक न्यूक्लियॉफाइल पूर्ण किंवा अंशतः सकारात्मक चाचण्याकडे आकर्षित होतो.
इंग्रजी शब्दकोशातील nucleophilicity व्याख्या
शब्दकोशातील न्यूक्लियओफिलिसिटीची परिभाषा म्हणजे न्यूक्लेओफिलिक, न्युक्लिओफिलिक प्रकृती असण्याची गुणवत्ता आहे.

Modern Physical Organic Chemistry
This trend reflects the relative basicities, as well. Below we will describe LFERs
for nucleophilicity and nucleofu- gality that correlate the pKas of the conjugate
acids of the nucleophiles and nucleofuges to sensitivity parameters (/Jnuc and /
JLc).

The Art of Writing Reasonable Organic Reaction Mechanisms
The nucleophilicity of a compound is measured by determining how reactive it is
toward CH3Br in water at 25 °C. Nucleophilicity bears some relationship toward
basicity, which measures reactivity toward H, but there are important differences.
