The acidities of ethyl, vinyl, and ethynyl derivatives containing heteroatoms of Groups 14, 15, and 16 of the periodic table are closely related, and reflect the differences in electronegativity of the CH3CH2-, CH2=CH-, and CH[triple chemical bond]C- groups.J. Guillemin...
Figure 01: Lemon Juice Has a High Acidity The periodic trends of acidity of chemical elements basically depend on theirelectronegativityvalues.The electronegativity of chemical elements increases from left to right of a period. If the electronegativity of an atom is higher, it can stabilize a negati...

pKa of Acids & Functional Groups | Overview & Examples from Chapter 13 / Lesson 7 41K Explore the concepts of pKa and pH values and how they relate to acids and bases. Learn the trends in pKa value for functional groups, acids, and bases with exa...
These trends change when the substituent is a methyl (silyl) group, with a significant decrease of its intrinsic acidity with respect to the Li, BeH and BH2 (Na, MgH and AlH2) derivatives, decrease that is even larger for the NH2 substitu- ent, for which the minimum acidity...
We plotted our data on this space to compare with previously found trends. Radioactive assessment of translation activity To probe protein synthesis, we opted to follow the incorporation of radioactive L-(4,5-3H)-leucine during stationary phase in complex MHB medium (±18 h after 1:100 ...
