Question

A valid Lewis structure of cannot be drawn without violating the octet rule. A) N13 B S02 E) CO2 62 A valid Lewis structure of cannot be drawn without violating the octet nule. A) NF3 DOCF4 63 Why don't we draw double bonds between the Be atomand the Ci atoms in BeC12? A That would give positiveformalcharges bo the chlorine atoms and a negative formal charge to the berylli There aren't enough electrons. That would result in more than eight electrons around beryllium. D That would result in more than eight electrons around each chlorine atom. E That would result in the formal charges not adding up to zero. 64 Bond enthalpy is A) always positive sometimes positive, sometimes negative D) always zero E) unpredictable 65 of the bonds CACC Cand C-o the CC bond is DO weakest shortest E) intermediate in both strength and length 66) Determining attioe energy from Bom-Haber cycle data requiresthe use of A) the octet nule law Periodic law D Hess's law

Explanation / Answer

61)
Answer: C

I has 7 valence electrons
5 more electrons will come from Cl
It will then have 12 electrons which violates octet rule

62)
Answer: B

Be has 2 valence electrons
2 more electrons will come from H
It will then have 4 electrons which violates octet rule
