Alkanes, a class of organic molecules, do not possess nucleophilic or electrophilic centers due to their saturated nature and lack of functional groups. They are composed solely of carbon and hydrogen atoms, connected by single bonds, which results in a relatively stable and inert structure. As a result, alkanes typically do not participate in reactions that involve nucleophiles or electrophiles.
Pyridine will add to carbon 3 in electrophilic reactions, such as Bromine addition. However in a nucleophilic reaction, such as seen in the Chichibabin reaction, carbon #2 and #4 are substituted such as if NH2 - attacked. Draw out the resonance forms and you will see this, or consult any Organic text under heterocyclic Chemistry.In a C3 attack, the electrophile will destabilize the C2 and C4 position, to a great extent since N lacks an octet in one of these resonance forms.In a nucleophilic addition, addition at C2 or C4 allows the negative charge to be shared by Nitrogen thus is preferred to the C3 attack.

The reaction in which one element or molecule is replaced or removed by another is called a substitution reaction. In this type of reaction, an atom or group of atoms in a compound is replaced by another atom or group. Substitution reactions are common in organic chemistry and can be classified into nucleophilic and electrophilic substitutions, depending on the nature of the reacting species.
Lipids are organic molecules that are naturally occurring and they are insoluble in water.
Organic molecules are essential. Almost everything you can touch or see is an organic molecule. Your body is composed primarily of water and organic molecules. Food is organic, and medicines are almost exclusively organic molecules. Most surfaces are organic, including wood and plastics. Without organic molecules, you wouldn't exist!
In organic chemistry reactions, nucleophilic addition to a carbonyl group occurs when a nucleophile attacks the electrophilic carbon atom of the carbonyl group, forming a new bond and resulting in the addition of the nucleophile to the carbonyl compound. This process typically involves the formation of a tetrahedral intermediate, which then collapses to yield the final product.
A nucleophile is a molecule or ion that donates an electron pair to form a new chemical bond with an electron-deficient atom, known as an electrophile. In organic chemistry, nucleophiles are important in reactions such as nucleophilic substitution and nucleophilic addition, where they attack and bond with electrophiles to form new compounds. This process is crucial for the synthesis of various organic molecules.
A nucleophilic substitution reaction involves the exchange of a nucleophile with a leaving group in a molecule. The nucleophile donates a pair of electrons to form a new covalent bond, displacing the leaving group. This type of reaction is common in organic chemistry and can proceed through different mechanisms, such as SN1 or SN2.

Sodium ethoxide is a strong base commonly used in organic chemistry reactions. It can react with various organic compounds to form new products through processes like nucleophilic substitution and elimination reactions. These reactions are important in synthesizing organic molecules and can lead to the formation of different functional groups.
t-Butyl iodide can be used in organic synthesis as a starting material for the preparation of various organic compounds. It can be used in reactions such as nucleophilic substitution, radical reactions, and as a source of t-butyl radicals. This compound is particularly useful in the synthesis of complex organic molecules due to its reactivity and stability.
Nucleophilic substitution occurs when a nucleophile (some species with an affinity for positive charge) attacks an atom that is electron rich (electrophile). The atom under attack cannot form additional bonds so must release a bond to another atom or side group that has less affinity for it. This often happens simultaneously in an SN2 type reaction but can also occur in the slower 2 step SN1 reaction. Now the nucleophile has taken the place of (substituted itself for) the atom or group with less affinity.

In this type of reaction, an atom or group of atoms in a compound is replaced by another atom or group.

The CHCHO functional group, known as an aldehyde, is significant in organic chemistry reactions because it is a versatile group that can undergo various reactions, such as nucleophilic addition and oxidation. Aldehydes are important intermediates in organic synthesis and are found in many natural compounds, making them essential building blocks for creating complex molecules.
NaOH, also known as sodium hydroxide, is a strong base commonly used in organic chemistry reactions. It serves as a catalyst or reactant in various reactions, such as nucleophilic substitution and elimination reactions. NaOH can also be used to deprotonate acidic compounds, facilitating the formation of new bonds and the synthesis of organic molecules.
