Question

Circle the stronger base in each pair

3. Circle the stronger base in each pair. (0.2 pts ea = 2.0 pts) a. (CH3) 3COK vs. CH3OK b. HCECNa vs. CH3CH2ONa C. NaNH2 vs. HCECNa d. NacN vs. NaI e. NaHCO3 vs. NaOH f. NaOH vs. CoH5CO2Na g. C6H5COzNa vs. CoH5ONa h. CH3CO2Na vs. CH3ONa i. CH3ONa vs. NaH j. NH3 vs. CH3CO2Na

Answer 1

Base is that electron rich species which can either accept Ht and donate é pair fast. Base which can donate electron pour more easely is stronger. (1413)( – 5 k e llgró kt bulkynen affect basicity. More bulky a base is more easily can it take a proton (CH3)₂ - c d e claro [basic nature] He=Ê theo sp hybridisation, spa hegtenidised, more electronegature can easily donate can't easely donate e" Pou, О. é pair e basic nature & UCET (chezesho EN HON HI (conjugate and] acidic nature: HI H EN [ More weaker and has basic nature, CN I Chronger conjugate base] I

c) NH₂ Нcsc- 12 ep3 trybridisahon, sp hybridisation, more electronegatue can easely donate - can't easely donate é pair erpan so, basic nature : NH₂> Heač
