- 1. Explain the following - why stearic acid has higher melting point than decanoic acid. - why benzoic acid has higher melting point than stearic acid. - why salicylic acid has higher melting point than benzoic acid. - why octane has a higher melting point than isooctane. - why 2,2,3,3-tetramethylbutane has the highest melting point among the three isomers of C8H18.arrow_forward1. Name the following alcohols and classify it as primary, secondary or tertiary.arrow_forward1,4-Pentadiene (CH2=CH-CH2-CH=CH2) is a liquid at room temperature and has a density of 0.66 g/mL and molar mass of 68.12 g/mol. In a laboratory experiment, 3.80 mL of this compound was treated with 4.80 mL of conc. H2SO4 (100% w/w; molar mass 98.08 g/mol). Note that the density of conc. H2SO4 is 1.84 g/mL. The resulting sulfate ester was then treated with 1.20 mL of water (molar mass 18.02 g/mol) affording, after work- up, 2,4-pentanediol (molar mass 104.15 g/mol) as the crude product. The crude product was then purified by simple distillation, which yielded 2.00 g of pure product. What is the theoretical yield of 2,4-pentanediol expressed in grams? Show calculations. What is the percentage yield of pure 2,4-pentanediol?arrow_forward

Provide a balanced chemical equation to show the reaction between 1,4-pentadiene and sulfuric acid. Do not use molecular formulas in the chemical equation except for sulfuric acid. b. What reactant is the limiting reagent in this chemical equation? Show calculations to support your answer.arrow_forwardName the alkene.arrow_forwardMake a model of cyclohexane and draw its shape. Comment on its bond angles and how easily the model fitted together. Draw the boat and chair conformations of cyclohexane. Which arrangement do you think is the most stable?arrow_forward
- Draw an isomer of C5H10O that contains an alcoholarrow_forwardThe condensed structural formula of an organic compound is CH3-CH2-CHBr-CHCl-CHCl-CHO. What is the name and type of this organic compound? 3-bromo-4,5-dichloro hexanal; aldehyde 4-bromo-2,3-dichloro hexanal; aldehyde 4-bromo-2,3-dichloro hexan-1-one; ketone 3-bromo-4,5-dichloro hexan-1-one; ketonearrow_forwardAlkenes can be converted to alcohols by reaction with mercuric acetate to form a β-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces the C–Hg bond to a C–H bond, forming the alkyl alcohol, a reaction called demercuration. Draw the structures of the Hg-containing compound(s) and the final alcohol product(s) formed in the following reaction sequence, omitting byproducts. If applicable, draw hydrogen at a chirality center and indicate stereochemistry via wedge-and-dash bonds.arrow_forward
