Write the equation showing the S-trans to S-cis equilibrium of the two conformations for a. (E)-1,3-pentadiene b. (Z)-1,3-pentadiene and which equilibrium will favor the s-tans conformation more strongly
The concentration of SO4 is .5 M in a certain solution of Al2(SO4)3. what is the molar concentration of Al in the solution
My paper says that will be only one isomer out of hexabromobiphenyl, C12H4Br6 And it states also that one phenyl group is still the active substituent when it is bromized. I wonder why it is only one isomer and I will be so thankful if you can dra..
