So for the multiple choice questions I got:
E/Z 1) C
Naming organic compounds 2) C
Lithium oxide 3a) D
Lithium oxide 3a) C
MgCl2 4a) B
Ionic Equation 4b) C
Vol of solution 4c) A
Bond Enthalpy 5) A
Bromine Water+Alkene 6) C
7) C
11) D
12) D
13) C
14) A
15) D
16) B
17) C
18) B
19) A
20) A
Section B:
21a The gaseous sample is bombarded with high energy electrons which knock electrons off of the atoms, creating ions with a positive charge
21aii Magnetic field causes deflection
21b The BROMINE one ew
21bii 80.1
There was another question here - can't remember it.
21c Test against a clean, controlled sample; and take into account that the athlete may have a prescription for it (that's wrong, I know)
21cii The athlete could face a ban from competing.
21ciii Use in forensics to identify the composition of an unknown compound
22a isotopes have the same number of protons, but a different number of neutrons
22aii structural isomers have the same molecular formula but a different arrangement of atoms in space
22b ∆_/ and ∆< (well, similar to that)
22c CnH2n
22c UV Light
22c CH2CH2+Br2 ----> CH2BrCH2Br
22c Cl---Cl -----> Cl. + Cl.
22c C4H8 + Cl. ----> C4H7. + HCl
C4H7. + Cl2 -----> C4H7
22d
Error 1: Partial charges are the wrong way around
Error 2: The arrow should go from the double bond to Chlorine, not the other way around
Error 3: The Chlorine in step 2 should have a lone par/negative charge to make it a Chloride
22e
22f? Tertiary carbocation (where there are three alkyl groups bonded to the charged carbon) is the most stable configuration
23a Cl---Cl and a kind of figure eight around it
23b Electrolysis equipment set up
23c
I really can't remember the rest, so please contribute! And also, can someone let me know the order of the MCQs, as there were some that weren't multipart questions.
