AQA A Level Chemistry- Organic
Chemistry comprehensive Questions and
Answers with Verified Solutions
Question 1:
Empirical formula
Answer:
The simplest whole number ratio of atoms of each element present in a
compound
Question 2:
How to find the empirical formula
Answer:
Obtain the mass of each element present in grams (Element % = mass in
g = m) Determine the number of moles of each type of atom present
Divide the number of moles of each element by the smallest number of
moles Convert numbers to whole numbers. This is the ratio of atoms
Question 3:
General formula
Answer:
The simplest algebraic formula that can describe any member of a
homologous series
Question 4:
Molecular formula
Answer:
The actual number of atoms of each element in a molecule
,Question 5:
Structural formula
Answer:
Uses letter symbols and bonds to show the arrangement of atoms in a
compound
Question 6:
Displayed formula
Answer:
Question 7:
Skeletal formula
Answer:
A simplified organic formula which only shows the carbon skeleton and
functional groups
Question 8:
Homologous series
Answer:
Family of chemical that differ from one another by a repeating unit, with
the same general formula and similar chemical properties
Question 9:
IUPAC rules of nomenclature order
Answer:
Longest carbon chain Unsaturation Functional groups Position of any
functional groups
, Question 10:
Free radical substitution
Answer:
Conditions: UV light Steps: Initiation Propagation Termination
Question 11:
Free radical
Answer:
An uncharged molecule, typically highly reactive and short-lived, having
an unpaired electron
Question 12:
Nucleophile
Answer:
A reactant that provides a pair of electrons form a new covalent bond
Lewis base
Question 13:
Electrophile
Answer:
A reactant that accepts a pair of electrons top form a new covalent bond
Lewis acid
Question 14:
Substitution
Answer:
Reaction in which one functional group is replaced by another
