Question

. CH 15 chem HW Determine which molecules are weak auds and weak bases, And place them in appropriate categories C'H, NH CH ₂ CO CH₃NH₂ Weak base Bronsted Lowry model dehne acids as it con donors and bases as Ht in acceptors The strength of an acid orb has to do with their degi of ionization in water, sto acids and based onze completely when dissolved wetter, whereas weak au and buses only partially CH₃COOH 5 weak bases 1. NH₂ 2. CH₃NH₂ 3. (CH3)₂NH 4. CH₃CH, NH₂ 5. Cu Hg NH₂

Answer 1

( Weak acids and weak bases. Á moderately weak Bronsted - Lowry acid has only a slight tendency to donate a proton whoras a weak bronsted - Lowry base is any species that is capable of accepting a proton. To classify 1 base رام CH3 NH3 + CH₂ Norge - CH₂NH2 +H+ methylamine (base) CH₂ N Hgt ut H₂O - CH₂ NH₃ + H₂O + and base conjugate conjugate. or we can say CH3 NH₂ + H₂O = on + CH₂ NH3 + Here methylamine accepts proton from water and therkby Beonseed Base. for Reverse Reaction, as CH₂ NH3 + donates proton w hydronice Therefore classify as bronsted acid. Hence C CH₃NH₂+ & Weak Acid H₂ & Weak Base. Scanned with CamScanner

CH₂ cool It can Base form CH₂ Look accept tht Mt & to Acid : Neak base CH2 200- +H+ - Criacoon. на сооч A celic Acid (ery coon) is a bronsted - Lowry acid because it is a proton donar, it donated its hydrogen ion to water. water is bronsted - howry base because it is proton accepton. The conjugate base is Chiz 200- . 4, Loo и u a wear aciol CH₂ woh - H+ + CH3 Coo- weak Acid to form. CH₂ coo can accept it back CH₂ cooh S.: CH₂ cool is weak base and I CH3 ooh is weak acia Overall CH3NH₂ + - weak Acid CH₂ WH2 - weak base CH3cO₂- & weak base Scanned with H2 cooh weak acio CamScanner
