What would be the carbon containing product in this SN2 reaction?

Question

CH3CH2-O(-) + CH3CH2CH2I ->

Give the major product:

ICH2CH2CH2CH2CH2F (KCN (1 eq)) DMF -->

the KCN is on top of the arrow, while the DMF is below the arrow.

I could really use some help! thanks!

Answer 1

CH3CH2-O(-) + CH3CH2CH2I-> CH3CH2OCH2CH2CH3

DMF is the solvent, so the nucleophile is KCN

Fluoride is too electronegative to be a good leaving group, so I think this is the product for your reaction.

ICH2CH2CH2CH2CH2F + KCN-> CNCH2CH2CH2CH2CH2F

Answer 2

Thank you for helping me out! I am having a tough time in this class and this was a big help
