Chemical formula methods are widely used for counting oxidation numbers. There are three types of chemical formula methods. They are molecular formula method, structural formula method, and Lewis formula method. Each type has its own rules and procedures, and they are difficult for students to fully understand and remember. In addition, the capability of the molecular formula method to assign mean oxidation number of organic carbons for organic molecules or molecular ions is limited. To overcome these drawbacks, this article explores a new half reaction approach, the carbon-atom method, which can count the mean oxidation number of organic carbons for both organic and bioorganic compounds. The quantitative relationships among the number of transferred electrons, change in oxidation numbers of organic carbons, and mean oxidation number of organic carbons can also be established by balancing half organic reactions. Furthermore, the mean oxidation number of organic carbons for any given organic or bioorganic compounds with known structural formulas can be determined by using the carbon-atom method and the fragmentation operation.","PeriodicalId":13866,"journal":{"name":"International Journal of Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83394992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The most common method to perform these two tasks is the oxidation number method, which combines mathematical operations and application of oxidation number. However, when oxidation number is not known, it is not applicable. Algebraic methods can balance all chemical reactions mathematically, but they cannot define redox reactions chemically. This article explores the electrical charge method for balancing, quantifying, and defining redox reactions. This method only requires the balancing of atoms and electrical charges. There is no need to determine oxidation number or count the number of transferred electrons. It works effectively in complicated cases where oxidation number is uncertain and where there are more than two sets of redox couples. Furthermore, the net-charge of a redox couple can function as a counting concept to determine its number of transferred electrons and change of oxidation numbers. The electrical charge method also initiates a new charge model, which complements the conventional electron model and oxidation number model, for defining redox reactions.","PeriodicalId":13866,"journal":{"name":"International Journal of Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73685937","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context that this current work applies quantum chemical method to study the interaction between some metals and four compounds with antidepression effect. Which compounds are clomipramine, imipramine, amoxapine and iproniazide. The inhibition properties of these compounds in acidic media were evaluated by density functional theory (DFT) with B3LYP functional in 6-31G(d,p) basis set. It was proved that these compounds have a strong electron donating and accepting capacity. This capacity is influenced by their substituents. The low energy gap (DE) values obtained denote that these molecules are highly reactive and can form coordination bonds for the establishment of a barrier on metal surface that could reduce corrosion process. Reactivity sites prediction were carried out by Fukui functions ( fk+, fk- ) and dual descriptor (∆fkr) ,it appears that the centers of nucleophilic attacks are in general nitrogen (N) atoms whereas the centers of electrophilic attacks are only carbon atoms (C).","PeriodicalId":13866,"journal":{"name":"International Journal of Chemistry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72771436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
