What type of isomers is shown in C2H2Cl2? Explain Do constitutional isomers have the same physical properties? Do geometric isomers have the same physical properties? Explain

Explain why stearic acid has higher melting point than decanoic acid. Explain why salicylic acid has higher melting point than benzoic acid. Explain why benzoic acid has higher melting point than stearic acid. Explain why octane has a higher melting point than isooctane. Explain why 2,2,3,3-tetramethylbutane has the highest melting point among the three isomers of C8H18

Explain the differences .  structural isomer and stereoisomer

What is the difference between a stereoisomer and a structural isomer?

Constitutional isomers are compounds which have the same molecular formula but different structural formulae. They are different compounds with different physical and chemical properties.a. Rearrange your model of n-hexane to make as many possible isomers of C6H14 as you can. Draw the structural formula and write down the IUPAC name for each isomer that you make.b. Constitutional isomers can also have different functional groups. Make all possible isomers of C3H8O. Write down the structural formulae and IUPAC names for all the compounds you make. Hint: Consider alcohol and ether functional groups.
