in an organic synthesis 62% yield of product is achieved. which of these conversions are consistent with this information
1) 74 g of butan2ol > 44.64 g of butanone
2)74 g of butan1ol > 54.56 g of butanoic acid
3) 74 g of 2methylpropane1ol > 54.56 g of 2methylpropanoic acid

Best ResponseYou've already chosen the best response.1You have to try all of them individually, use the equation at the bottom. Assuming that the coefficients for the reactants and products involved are 1... \(\sf moles_R=moles_P\) sub in: \(\sf moles_R=\dfrac{mass_R}{Molar~mass_R}\) \(\sf \dfrac{mass_R}{Molar~mass_R}=\dfrac{mass_P}{Molar~mass_P}\) therefore: \(\sf mass_P= \dfrac{mass_R*Molar~mass_P}{Molar~mass_R}\) this is the theoretical yield, since only 60% was made, multiply by 0.6. So, \(\sf \large mass_P= 0.6*\dfrac{mass_R*Molar~mass_P}{Molar~mass_R}\)

Best ResponseYou've already chosen the best response.0For one i tried (74×72)/74 and then multiplied by 0.6 it gives 43.2. Where am i wrong?
