In case of formation of two isomers of alkenes, explain which is formed in greater proportion CH3 ofi H3C- -Br CH3 EtOHarrow_forwardThe 2-propenyl cation appears to be a primary carbocation, and yet it is considerably more stable than a 1° carbocation such as the 1-propyl cation. CH,=CH-CH, CH, CH, CH," 2-Propenyl cation 1-Propyl cation How would you account for the differences in the stability of the two carbocations?arrow_forwardThe reaction shown below is carried out in two stages. In the first, the two reactants are combined in tetrahydrofuran (THF) solvent to form a neutral adduct. Aqueous acid is then added to hydrolyze this initial adduct, giving the final product.

- When 2-bromo-2-methylbutane is treated with a base, a mixture of 2-methyl-2-butene and 2-methyl-1- butene is produced. When potassium hydroxide is the base, 2-methyl-1-butene accounts for 45% of the product mixture. However, when potassium tert-butoxide is the base, 2-methyl-1-butene accounts for 70% of the product mixture. What percent of 2-methyl-1-butene would be in the mixture if potassium propoxide were the base? base Br A. Less than 45% B. C. 45% Between 45% and 70% D. More than 70%arrow_forwardWrite an equation for the acid-base reaction between 2,4-pentanedione and sodium eth- oxide and calculate its equilibrium constant, K.

The crystals produced are insoluble in organic solvents but freely soluble in water. They have a melting point of 203 °C. There is an instantaneous precipitate formed with silver nitrate solution. Catalytic hydrogenation gives cycloheptane. What is the crystalline compound? Why does it have these unexpected properties? heat 1 equiv Br2 dibromide crystals - HBr tropilidenearrow_forward

Would H₂O be an appropriate solvent? Explain your rationale.arrow_forwardA compound X of molecular formula C7H14 when hydrogenated produces 2,4-dimethylpentane and when hydroborated the obtained alcohol is 2,4-dimethyl-1-pentanol. a. What is the structure of X? b. If X is reacted with H2O catalyzed by H2SO4, what product is obtained? Write the structure, give the name, and write the complete mechanism, step by step of this reaction, in such a way as to explain the formation of the compound (DO NOT FORGET THE CORRECT USE OF ARROWS!).arrow_forward
