Question 1

solubility of silver(i) halides

Answer 1

Cl->Br->I
decreasing solubility
increasing covalent

Question 2

2,4 DNP

Answer 2

> orange/red ppt for carbonyl group
mp of derivative
compare to known

Question 3

IE

Answer 3

> further from nucleus/ shell/radius/shielding
cations/ proton electron ratio
greater/ lesser nuclear attraction

Question 4

intermolec forces q

Answer 4

> identify strongest bonding only
BP inc as electroneg inc
compare

Question 5

D2O use

Answer 5

to identify NH and OH peaks

Question 6

hetero/homolytic fission

Answer 6

fission:
COVALENT bond breaks
hetero:
one bonding atom receives both electrons
homo:
each bonded atom receives one electron

Question 7

CDCL3 use

Answer 7

solvent in NMR

Question 8

drawing condensation polymers

Answer 8

ester linkage in middle and also on ends split into carbonyl on one side and ether on other

Question 9

limitations of free radical sub

Answer 9

further substitution/ mixture of products
substitution at different positions

Question 10

GC blurt

Answer 10

RT is time spent in the tube
-can be used to identify compound
REL PEAK AREA
-proportions of compounds
- use calibration curves for conc

Question 11

TLC chromatograms

Answer 11

Rf = moved my spot/ moved by solvent front
dot size represents proportion

Question 12

DBE
(double bond equivalent/ degree of unsaturation)

Answer 12

one for each double bond
one for each ring
so napthalene is 8

Question 13

condtitions for e/z isomerism

Answer 13

both carbons in the double bond have 2 different groups

Question 14

x-block element

Answer 14

has its highest energy electron in an x subshell/orbital

Question 15

transition element

Answer 15

forms ions with incomplete d-subshell/ d-orbitals

Question 16

why is Sc and Zn not transition

Answer 16

SC 3+ has empty d subshell
Zn 2+ has full d subshell
