Do the line-angle formulas in each pair represent the same compound or constitutional isomers? (a)      (b)

Course Hero · Accepted Answer

The line angle formula represents the carbon at the end of the line and each corner of the line. This type of representation will not show hydrogen atoms in the structure. Constitutional isomers are compounds having the same molecular formula but differ in connectivity between the atoms. These compounds will differ in terms of the position of branches or based on bonds between the atoms, double, single, or triple bonds. The compounds in the pair have the same molecular formula C8H18 but differ in the position of branches. According to IUPAC naming, the longest chain is of 6 carbon atoms in both molecules, but in the first one from left, the two methyl groups are in the position (3,4) while in the second, it is (2,4). For the given pair of compounds, both the molecular formula and structural arrangement of atoms remain the same, but the connectivity of groups is different.
