Hello.
I'm curious about the pKa of DEET(C12H17NO).
As I know, pKa means how weak or strong an acid is.
However, DEET has no carboxyl function or H giving position.
Can you help and explain this?
Thank you so much.
DEET ( diethyltoluamN,N-Diethyl-meta-toluamideid), is a insect repellents and is amide a neutral compd.hence has low acidic behaviour (low pKa).
