The less stable isomer corresponded to structure 2N (030730.four Kcal/mol), as a consequence from the steric hindrance The energy values of each isomer in the same level are summarized in Table 1. The significantly less stable by the nearest atoms. structure 2N (,030,730.four kcal/mol), as a consequence of Kcal/mol), with the isomer corresponded to In contrast, the most stable isomer was 2H (030762.1 the steric hindrance chlorine and hydroxyl groups as expected in line with this class of addition anti position, with an by the nearest atoms. In contrast, probably the most stable isomer was 2H (,030,762.1 kcal/mol), with all the power difference of 31.77 kcal/mol. As a result, the structure 2H was made use of in subsequent calculations and chlorine and hydroxyl groups as anticipated based on this class of addition -anti position, with an this isomer is named as 2. power difference of 31.77 kcal/mol. Therefore, the structure 2H was utilized in subsequent calculations andthis isomer is named as two.Table 1.

Reaction Mechanism two.two. Reaction Mechanism In order elucidate the the formation method of 2, two pathways were thought of according To be able to to elucidate formation course of action of two, two reaction reaction pathways had been viewed as in accordance with the previously reported typical addition mechanism [10], a single with only ionic species of for the previously reported standard addition mechanism [10], a single with only ionic species with the HOCl the HOCl (Path second, the second, thinking about the whole HOCl molecule (Path B). These are (Path A), plus the A), and considering the entire HOCl molecule (Path B). These two pathways two pathways are shown in Figure it is actually worth mentioningworth mentioning that each pathways have been shown in Figure 3. Moreover, three.
