Chapter 15 Haloalkanes

Question 1

Normal ozone formation

Answer 1

O2> 2O O2+O >

Question 2

with CFCs

Answer 2

CF2Cl2 > CF2Cl*
Propagation step 1 Cl* + O3 > ClO* + O2
step 2 ClO* +O > Cl* +O2
Overall O3+ O > 2O2

Question 3

with Nitrogen oxide

Answer 3

Propagation step 1 NO* + O3 > NO2* + O2
step 2 NO2* + O > NO* +O2
Overall O3+ O > 2O2

Question 4

nucleophile

Answer 4

An atom (or group of atoms) which is attracted to an electron-deficient centre or atom, where it donates a pair of electrons to form a new covalent bond.

Question 5

nucleophilic substitution

Answer 5

A reaction in which a nucleophile is attracted to an electron-deficient carbon atom, and replaces an atom or group of atoms on the carbon atom.

Question 6

hydrolysis

Answer 6
