  • Hydration via Hydroboration-Oxidation - Socratic
    What stereoisomers are obtained from hydroboration–oxidation of cis -2-butene? What stereoisomers are obtained from hydroboration–oxidation of cyclohexene? There is only one alkyne that forms an aldehyde when it undergoes the mercuric-ion-catalyzed addition of water What is this alkyne?
  • Please explain enantiomerisim and its condition? - Socratic
    A carbon atom with FOUR substituents, CR1R2R3R4, can exist as LEFT-HANDED or RIGHT-HANDED stereoisomers depending on the geometry The interchange of ANY TWO substituents results in the ENANTIOMER (and of course we do this on paper not in glass); interchange again, and you get the enantiomer of an enantiomer, i e the original isomer

  • Question #30788 - Socratic
    From the balanced equation 46 grams of Nareacts with 71 grams of Cl_2 gas to form 117 grams of NaCl (numbers obtained from the molar mass atomic mass) The law of conservation of mass says that the mass of reactants equals the mass of products We can say that 2 moled of Na reacts with 1 mole of Cl_2 molecule to form 2 moles of NaCl We see the 117 g of NaCl is 117 g 117 g mol = 1 mol (Mole
  • Question #7d76d - Socratic
    Here's what I got Interestingly enough, you don't need to know the density of the solution to calculate its molality and the mole fraction of hydrochloric acid, "HCl", your solute All you need to know here is the solution's mass by mass percent concentration, "% m m", which is said to be equal to 36% Now, to make the calculations easier, pick a sample of this solution that has a mass of
  • Question #8b990 - Socratic
    Not sure if the following helps? Although some of the earliest views of oxidation related to a process where oxygen is added, it is more widely defined as when an atom, ion or molecule loses an electron Conversely, reduction is when an atom, ion or molecule gains an electron The acronym "OIL RIG" is used to help remember this : "Oxidation Is Loss, Reduction Is Gain" You may first have heard
