Q

What are nucleophiles?

A

= all of them have lone pair of electrons
= lone pair of electrons is attracted to an electron defficient carbon atom- have a partial or full pisitive charge
= donates their lone pair of electrons to form a covalent bond between nucleophile and carbon atom

Q

What happens when an HO:^- ion reacts with a haloalkane?

A

= lone pair of electrons on the OH- ion are attracted to the electron defficient carbon atom
=nucleophile donates it’s electrons to the carbon to form a covalent bond with the electron defficient carbon atom
= carbon can have a maximum of 4 covalent bonds
= covalent bond between the carbon and halogen breaks pair of electrons moving to the halogen atom
= hetreolyric fission

Q

How do we represent the movement of a pair of electrons?

A

= curly arrow
= from the lone pair of electron and end at the electron deffecient carbon atom

Q

What are the conditions needed for this reaction?

A

= aq solution of OH ions
= haloalkanes are insoluable in water so ethanol needs to be added so it react with aq OH ions
= heat reaction under reflux to increase the rate
