Carbon-Carbon Bond Formation Flashcards
1
Q
Why is it important for chemists to be able to adapt the length of hydrocarbons?
A
- Some medicines work by fitting into an enzyme in bacteria to stop it from working properly, molecules need to be the right shape.
- when manufacturing fuel you need to be able to change the carbon chain length to get your desired product.

Q
A)What does a reaction between a haloalkane and cyanide ions in ethanol produce?
B)what are the conditions required?
A
A)A nitrile group
B)A solution of sodium or potassium cyanide in ethanol mixed with a haloalkane
-heated under reflux
3
Q
What type of reaction occurs when forming a nitrile group from a haloalkane and cyanide ions in ethanol?
A
- A nucleophilic substitution reaction(SN2)
- the nucleophilic cyanide ion attacks the delta positive carbon
- Cl is substituted with a nitrile group
