NUCLEOPHILICITY SÖZCÜĞÜ İNGILIZCE DİLİNDE NE ANLAMA GELİR?
nükleofil
Bir nükleofil, bir reaksiyona karşı bir kimyasal bağ oluşturmak üzere bir elektrofile bir elektron çifti bağışlayan bir kimyasal türdür. Serbest elektron çifti veya en az bir pi bağına sahip tüm moleküller veya iyonlar nükleofiller gibi davranabilir. Nükleofiller elektronlar bağışladığı için tanım gereği Lewis üsleri. Nükleofilik çekirdeklerin bir nükleofilin afinitesini tanımlar. Nükleofiliklik, bazen nükleofil mukavemet olarak adlandırılır, bir maddenin nükleofilik karakterine atıfta bulunur ve genellikle atomların afinitesini karşılaştırmak için kullanılır. Alkoller ve su gibi çözücülerle nötr nükleofilik reaksiyonlara, solvoliz adı verilir. Nükleofiller, nükleofilin yerini alabilir, böylece bir nükleofıl tam veya kısmi pozitif yüke çekilir.

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.
