(4Z)-2,4-diethyl-1,4-hexadiene: I need to draw the structure, but I don't understand what "4" Z means (I know what is Z however). It is Z in relation to what?

Thanks!

E-Z configuration, is the IUPAC method of describing the geometrical isomers, the absolute stereochemistry of double bonds in organic chemistry.

It can be used to describe double bonds having two, three or four substituents.

If the two groups of higher priority are on opposite sides of the double bond, the bond is assigned the E configuration E (E = entgegen, German: German word for "opposite").

If the two groups of higher priority are on the same side of the double bond, the bond is assigned the Z configuration ( zusammen, German: the German word for "together").

i need to recrystallize 1,4-dichlorobenzene (started with 1:1 mix of 1,4-dichlorobenzene and 4-aminobenzoate then dissolved in diethyl ether and separated by adding HCl). the solvents I have available are 99% ethanol, methanol, water, sodium hydroxide, and sodium sulfate) Do I need to dry the product with sodium sulfate and the rotovap before recrystallizing? and what solvent(s) would work to recrystallize after rotovap?

I need to provide proof that these statements are FALSE. But I don't always understand why they are false. 1.

(dont the skeletal muscles just need the tiniest bit of Ca to use the DHP channels?) 2.

The bold part is what I don't understand. A country with a negative current account is because NX < 0 loanable fund mrkt; open econ. If country M>X, NX=<0 so S-l=<0 which means there is more investment into the country than domestic savings because NX is matched with a counter-flow that is NFI (Net Foreign Investment). There is going to be NFI in a country that imports more than it exports Ex: US. They import more than they export. Meaning...
