To solve this problem, we need to determine the correct structure of tribromooctaoxide.$\newline$The chemical formula for tribromooctaoxide is $Br_3O_8. \newline$This compound consists of three bromine atoms and eight oxygen atoms.$\newline$Let's analyze the given options:$\newline$Option 1:$\newline$• The structure shows three bromine atoms connected by single bonds.$\newline$• Each bromine atom is bonded to two oxygen atoms, forming $BrO_3$ units.$\newline$• This matches the formula $Br_3O_8. \newline$Option 2:$\newline$• The structure shows three bromine atoms, but the oxygen arrangement does not match $Br_3O_8. \newline$• It has extra negative charges, which are not expected in the neutral compound.$\newline$Option 3:$\newline$• The structure shows three bromine atoms, but the oxygen arrangement does not match $Br_3O_8. \newline$• It has extra negative charges, which are not expected in the neutral compound.$\newline$Option 4:$\newline$• The structure shows three bromine atoms, but the oxygen arrangement does not match $Br_3O_8. \newline$• It has extra negative charges, which are not expected in the neutral compound.$\newline$Therefore, the correct structure of tribromooctaoxide is given by Option 1.
