Acoording to the IUPAC rules for nomenclature of the halo compounds the $\ce{Cl}$ here is treated like $\ce{CH3}$. And also according to rule, the double bond have preference over the groups other than functional groups.

The pubchem website has given Platensimycin IUPAC name, $3$-$[3$-$[(1S,5S,6R,7S,9S,10S)$-$5,9$-dimethyl-$4$-oxo-$8$-oxatetracyclo$[7.2.1.1^{7,10}.0^{1,6}]$tridec-$2$-en-$5$-yl]propanoylamino]-$2,4$-dihydroxybenzoic acid (see attached picture): Accordingly, since https://pubchem.ncbi.nlm.nih.gov is usually updating data according to the changes, I believe ...

An elder version of Chemdoodle (8.1.0) suggests a name slightly different from the one in the comment by @KarstenTheis, 8-Oxotetracyclo$[7.2.1.1^{7,10}.0^{1,6}]$-tridec-2-3n-4-one. It may be that I erred while drawing the molecule into the sketcher, hence for a xcheck the screen photo below. The yellowish' spheres indicate Chemdoodle's selection for the ...

Name of this complex is. Mercury tetrathiocyanato cobaltate (2) . First take the stable oxidation state one . Another factor is Hg +2 a soft acid and SCN- is a soft ligand their is soft -soft interactions... Cobalt is in +2 oxidation state which is a borderline acid but due to symbiosis it behaves more like soft acid than hard .

As you have correctly stated in the question, the $\ce{-COOH}$ group has higher priority than the $\ce{-COOR}$ group. In fact, the $\ce{-COOH}$ group has the highest priority (excepting cations) in IUPAC nomenclature. The $\ce{-COOH}$ group should be included as the suffix of the parent chain, while the $\ce{-COOR}$ is indicated using a prefix. In fact, ...

Interesting question but the sad answer is we will never know the true story. Here is the original text (thanks to Google Books) dated 1863, right from the horse's mouth Adolf von Baeyer. Dieser Gedanke hat mich bei der folgenden Arbeit geeitet (spelling?), und ich habe mich zunächst bemüht, die Kenntnis des Materials zu vervollständigen. Man wird ...

Calling gasoline "octane" would be mistake. There are a few widespread misconceptions about this topic. Most importantly, many people think that gasoline contains large amounts of octane, mainly because of the frequent mentioning of the high octane number of gasoline. Accordingly, many textbook chapters about combustion use the reaction of octane as example ...

Octane number is a scale that is used to determine the quality of a fuel. It may be defined the percentage of isooctane by volume in a mixture of isooctane and n heptane that has the same anti knocking properties as fuel under examination. Petroleum or crude oil is obtained in complex mixture of hydrocarbons (chiefly aliphatic with small amount of ...

According to IUPAC Nomenclature rules, the carboxylic acid functional group carbon is included in the base aliphatic chain if one or two carboxylic acid functional groups are present and the standard suffix '-oic acid' is used. For three or more carboxylic acid groups in an aliphatic chain, the carboxylic acid carbons are excluded and the suffix 'carboxylic ...

As already explained in a related answer, the most important simplified criteria for the numbering in such cases are: lower locants for the principal characteristic group that is expressed as suffix lower locants for multiple bonds lower locants for prefixes lower locants for substituents cited first as a prefix in the name The corresponding actual wording ...
