DFT calculations provide significant informations on stable geometry‚ vibrational tendency‚ interaction behavior‚ reactive nature and possible local reactive sites of a molecular system. The local reactivity descriptors pave the understanding towards the interaction between biologically privileged molecular systems‚ and establish the correlation between the biological system and material science which leads to the search of new pharmaceutical compounds

Though cis-platin is highly effective‚ its counterpart trans-platin is counterintuitively not (7). Trans-platin is highly reactive with the environments that lead to reaching the DNA‚ and this reactivity results in the totality of the administered compound becoming deactivated prior to reacting with the DNA (9). Also the DNA lesion caused by cis-platin on the 1‚2 intrastrand crosslinks between adjacent purines is an act that trans-platin cannot do when looking from a stereochemical perspective (9)

table‚ whether it is defined through the size of the atoms or the first ionization energy that may occur‚ many other trends can be found simply looking horizontally or vertically on to the table. As you look from left to right you can see that the reactivity of the elements increase‚ this is due to the number of electrons increasing on the shell. This also once you go down the table; the shells become further and further apart from the nucleus so the bonding is a far weaker‚ the orbitals also increase

Researchers have explored the effects of child care on numerous aspects of development‚ although research on cognitive and language development as well as social-emotional development and stress reactivity have been especially informative. Scholars and politicians who address the value and relevance of child care have been particularly apprehensive that children cannot maintain supportive relationships with their parents when they attend child care

Comparison of Three Isomers of Butanol Introduction An alcohol’s reactivity is determined based on the attachment of their hydroxyl functional group. The location of this hydroxyl functional group will impact the molecular structure of the alcohol‚ making it either primary (1° )‚ secondary (2° )‚ or tertiary (3° ). The purpose of this experiment is to observe and predict the reactions that take place between all three alcohols and an oxidizing agent‚ as well as to test our theories of how the

B. Chromic Acid Test/ Jones Oxidation This test is based on the reduction of chromium(IV)‚ which is orange‚ to chromium(III)‚ which is green‚ when an alcohol is oxidized by the reagent. A change in color of the reagent from orange to green represents a positive test. Primary alcohols are oxidized by the reagent to carboxylic aicds; secondary alcohols are oxidized to ketones. Tertiary alcohols are not oxidized at all by the reagent. Hence‚ this reaction can be used to distinguish tertiary alcohols
