We would just like a second opinion. 4. A leaving group is a nucleophile acting in reverse; it accepts a lone pair as the bond between it and its neighbor (usually carbon for our purposes) is broken. bad pKa 35. The -OH is a better leaving group according to acid-base Lewis theory because it tends to form quickier the corresponding conjugate acid in comparison with -NH2 and also because the unstability. the same pressure? A weather balloon with a volume of 3.40774 L Why would leaves in a K+ solution have more open stoma than leaves in a Na+ solution. NaOH + HCl -----> NaCl + H2O A. Question. I was under the impression that OH was a better leaving group than NH2. Write the expected electron configurations for each of the following atoms: Cl, As, Sr, W, Pb, Na+, I-, Mg 2+, S2-, and Cf.? what is... A: Since the given incorrect electron configuration of Al is  ? In chemistry, a leaving group is a molecular fragment that departs with a pair of electrons in heterolytic bond cleavage.Leaving groups can be anions, cations or neutral molecules, but in either case it is crucial that the leaving group be able to stabilize the additional electron density that results from bond heterolysis. A: Temperature programming is used to run a large fraction of all gas chromatography. C. An Snl reaction is a concerted reaction and carbocation is the intermediate. In this the tempe...

The “happier” and more stable that lone pair is, the better a leaving group it will be. Still have questions? Under basic conditions, OMe- generally doesn't leave, but Grignard is such a strong nucleophile / base that it forces the OMe- to leave. A. Notably, changing the leaving group's identity (and willingness to leave) can change the nature of the mechanism in elimination reactions. An could you please explain? © 2003-2020 Chegg Inc.
