Yeah this was a time consuming question. Anyway so this is what I did. You do the same thing for the diethyl ether, you have to write out the equation and all. Obviously all this working is not required but I cant do any calculations without writing it down.

The answer to this is B.
Why isn't it A? as the question says ' some covalent character' doesn't this imply least covalent character?

Why are we dividing y by 2? although y is the enthalpy change of reaction and it doesn't have to be per mole?
NaCl is a crystal ionic lattice. It possesses only ionic bonds.
MgCl2 too is a crystal lattice. There are ionic bonds between Magnesium and Chlorine, because Mg is a metal, and Cl is a non-metal. However, since there are two atoms of chlorine in every molecule of MgCl2, there has to be some bonding between Cl2 as well. Thus, between Clorine, there will be Covalent bonds (Instantaneous Induced Dipole Forces of Attraction). Thus the compound will exhibit SOME Covalent Character.

Right, but isn't it true that covalent character is due to the polarising power of the metal ion? and Na is less polarising power then Mg because of less charge so it would have less covalent character while Mgcl2 will have more :S so shouldn't the answer be A

Polarizing effect is due to the difference in the electronegativity. Covalent character is not due to the polarizing power of the metal ion. It isn't necessary. Covalent character is present in HCl. There is no metal ion in this case.

i think you haven't came across it yet :0 because there is no covalent character in covalent compounds.. its a term used for ionic compounds

The answer is C, (X+Y)/2. This is because "2" moles of C2H4 are being combusted

I didn't get it.
Y is the enthalpy change of the reaction na so why are we dividing y by 2?

Y is the enthalpy change of formation of C4H8 from C2H4.Formation of C4H8 and combustion of C4H8 = X+Y.

B & A are trans isomers. but as mentioned in the question the fat is optically active which means it should have chiral carbon. "R1 & R2 are two different chains so only B is the answer.

can u indicate on the picture the chiral carbon and also how u identified A and B to be cis trans isomers. I find these structures very confusing nd can't really find the isomers in them.
thankyou ۔
thankyou ۔
