I also agree with @Loong, the suggested name "6-ethenyl-4-(prop-2'-enyl) octa-6-en-3-ol" seems incorrect. The correct name for this compound should be (7E)-4-(but-3-en-1-yl)-6-ethenylnon-7-en-3-ol, as @Loong mentioned. In this compound, the longest carbon chain has 10 carbon atoms, but we select the carbon chain with 9 carbon atoms as it has a ...

You have correctly ideentified and numbered the parent structure (the longest chain), which is undec-3-yne. Including the substituent groups, the complete name is 10-bromo-5-(butan-2-yl)-2-methylundec-3-yne. Note that names for simple substituent groups derived from acyclic hydrocarbons with the free valence not at the end of the chain are generically called ...

The authoritative source Nomenclature of Inorganic Chemistry, IUPAC Recommendations 2005 (Red Book) lists $\ce{H[AuCl4]}$ as an example of a salt in the subsection IR-4.4.3.4 Generalized salt formulae [1, pp. 61–62]. Further, introduction to the section IR-8 Inorganic Acids and Derivatives underlines that IUPAC nomenclature is established from composition ...

In regards to the symbolic representation of units of molarity, molality and molar mass. Molarity: $\mathrm{mol\, L^{-1}} => M\\\\$ Molality: $\mathrm{mol\, Kg^{-1} }=> m\\\\$ Molar mass: $\mathrm{u} => M(M_r)\\\\$ Regarding molality being defunt when molarity is known. No, molality is not a defunt when we know the molarity. Molarity is defined as ...
