Lda is a strong base
WebIt can withdraw electrons by virtue of hyperconjugation into sigma* molecular orbitals. A simple way to think about it is that nitrogen is less electronegative than oxygen, thus it cannot stabilize negative charge as well. Since the nitrogen anion is not as stabilized, it is more reactive and thus a stronger base. WebA: Stronger base among the two can be found out by observing the electron density provided by each… Q: In each equation, label the acids, bases, and conjugate pairs: (a) NH4+ + CN- ⇌ NH3 + HCN (b) H2O +… A: The acid, base and conjugate pairs have to labelled. Q: Give the conjugate acid of PO4.
