Chemical Properties of Pyridine

Pyridine is a pi-deficient heterocycle with lower electron cloud density than benzene so its electrophilic substitution activity is also lower than benzene which is equivalent to nitrobenzene Because of the passivation of nitrogen atoms on the ring the conditions of electrophilic substitution reaction are harsh and the yield is low

Table of Densities of Common Substances

Here's a table of densities of common substances including several gases liquids and solids Density is a measure of the amount of mass contained in a unit of volume The general trend is that most gases are less dense than liquids which are in turn less dense than solids but there are numerous exceptions For this reason the table lists density from lowest to highest and includes the

Effects of Heteroatoms on Aromatic π−π Interactions

Heteroatoms are found in many noncovalent complexes which are of biological importance The effect of heteroatoms on π−π interactions is assessed via highly accurate quantum chemical computations for the two simplest cases of interactions between aromatic molecules containing heteroatoms namely benzene−pyridine and pyridine dimer

Theory for WHAT IF options

This yields pyridine The 'pyridine' nitrogen differs from the amide nitrogen in the electron distribution It has one electron in the p orbital and two in an sp 2 orbital This is the arrangement that we rejected in amides because it would lead to unpaired electrons Here one electron is actually what is asked for by the rest of the molecule

Pyrazole: synthesis and reactivity

Pyrazole is an aromatic heterocyclic compound characterized by a five membered ring with formula C 3 H 3 N 2 H The two nitrogen atoms are adjacent and as we saw for imidazole one of them is a pyrrole-like nitrogen while the other is a pyridine-like nitrogen In order to quickly refresh your memory a pyrrole-like nitrogen is a non-basic nitrogen with a lone pair involved in aromaticity
