Pka value ethyl acetate
WebFrom my understanding, esters are actually an ERG and ERG’s make acidic protons less acidic. Edit: EWG’s make acidic protons more acidic. So that’s why ethyl acetate would be less acidic and therefore have a higher pka than acetone. If this is wrong, anyone can feel free to respond! WebEthyl acetate is the acetate ester formed between acetic acid and ethanol. It has a role as a polar aprotic solvent, an EC 3.4.19.3 (pyroglutamyl-peptidase I) inhibitor, a metabolite …
