Summary
A new quantitative model, the quantitative descriptor-based alkane nucleophilicity (QDEAN) model, predicts alkane C-H bond reactivity. This model uses six structural descriptors to accurately calculate alkane nucleophilicity for various C-H bonds.
Area of Science:
- Organic Chemistry
- Computational Chemistry
Background:
- Understanding alkane reactivity is crucial in organic chemistry.
- Quantifying nucleophilicity of C-H bonds presents a significant challenge.
Purpose of the Study:
- To develop the first quantitative model for predicting alkane nucleophilicity.
- To establish a method for calculating the reactivity of alkane C-H bonds.
Main Methods:
- Statistical analysis of reactivity data for 29 alkane C-H bonds.
- Correlation of experimental reactivity with 86 structural and topological descriptors.
- Development of the quantitative descriptor-based alkane nucleophilicity (QDEAN) model.
Main Results:
- The QDEAN model accurately reproduces the relative reactivity of alkane C-H bonds.
- The model utilizes only six structural/topological descriptors.
- Reactivity can be calculated from basic alkane structural parameters.
Conclusions:
- The QDEAN model provides a simplified yet effective approach to predict alkane nucleophilicity.
- This model facilitates the study of alkane C-H bond functionalization reactions.

Olefins, which are unsaturated hydrocarbons containing one or more carbon–carbon double bonds, are broadly divided into alkenes and cycloalkenes. The general chemical formula of an alkene is CnH2n.
Doubly bonded carbons are sp2 hybridized and have a trigonal planar geometry. The double bond is composed of a σ bond formed by the overlap of hybrid orbitals and a π bond produced by the lateral overlap of unhybridized 2p orbitals on both the carbons. Each carbon atom is...

The relative stability of alkenes can be determined by comparing their heats of hydrogenation. The lower heat of hydrogenation indicates the more stable alkene. The three main factors determining the relative stability of alkenes are i) the number of substituents attached to the double-bond carbon atoms, ii) hyperconjugation, and iii) the stereochemistry of the double bond.

Introduction:
In nature, compounds containing both carbon and hydrogen are known as "hydrocarbons". Aliphatic hydrocarbons are compounds whose molecules contain saturated single bonds (i.e., alkanes) or unsaturated double or triple bonds. Alkenes contain carbon–carbon double bonds and have a structural formula CnH2n. Unsaturated hydrocarbons containing carbon–carbon triple bonds are called "alkynes" and are structurally represented by the formula CnH2n-2.

The acidic strength of hydrocarbons follows the order: Alkynes > Alkenes > Alkanes. The strength of an acid is commonly expressed in units of pKa — the lower the pKa, the stronger the acid. Among the hydrocarbons, terminal alkynes have lower pKa values and are, therefore, more acidic. For example, the pKa values for ethane, ethene, and acetylene are 51, 44, and 25, respectively, as shown here.

In the late 19th-century, the number of new chemical compounds discovered increased tremendously. Hence, the necessity arose to develop a naming system for the systematic nomenclature of these newly discovered compounds. IUPAC (International Union for Pure and Applied Chemistry), established in 1919, sets rules for the nomenclature.
The alkane nomenclature considers the length of the carbon chain, the number, and the location of the substituent to arrive at its systematic name. The IUPAC...

The formation of carbon-carbon bonds leading to the creation of the carbon chain is the basis of organic chemistry. August Kekulé and Archibald Scott Couper independently developed this idea of carbon chain formation.
