Question 1

What is an Alkene?

Answer 1

Alkenes are unsaturated hydro carbon molecules containing carbon double bonds.

General formula - CnH2n for a straight chain molecule

Question 2

Nomanclature is the same for Alkenes - Except for 1) & 2)

Answer 2

1) The suffix ‘ene’ is replaced with ‘ane’

2) The double bond is numbered in the molecule. Trying to get the smallest number for the double bonds.

Question 3

Alkyl Groups

Answer 3

A functional group of an organic compound - that contains only carbon + hydrogen atoms.

Which are arranged in chains

Question 4

Diene

Conjugated Diene

Answer 4

An alkene with two double bonds.
(Think man falling)

A diene with a single bond between the double is a conjugate diene.

Question 5

A nucleophile

Answer 5

A molecule with a free pair of electrons + sometimes a negative charge that seeks out partially or completely positive charge species

Question 6

Morkovnikoffs Rule

Answer 6

The nucleophile will be bounded to the most substituted carbon. (Fewest hydrogens attached)

Equivalently the electrophilic will be bonded to the least substituted carbon. (Most hydrogens attached)

Question 7

Oxidation

Answer 7

Alkenes can undergo a variety of reactions in which the carbon carbon double bond is oxidised.
