Oh ok, Umm what did u guys get for lattice energy value?

Posted from TSR Mobile

-1046.. or 1064 not sure but around that value :P

Haha yea what do you think the grade bondaries will be

Probaby something like 62-65

Okay for the orbitals question I got 10, 6, 18 idk if I'm right, the lattice enthalpy was -1046kj/mol, the mean bond enthalpy value calculated was -413, the bond enthalpy for C-C was -347, I wrote Br(-) for the electrophile I think I'm wrong there

yes you are wrong. electrophiles are negative charge LOVERS!so obviously positive!
