Get started for freeButyric acid, the compound responsible for the unpleasant odor and taste of sour milk, has a pKa value of 4.82. What is its Ka value? Is it a stronger acid or a weaker acid than vitamin C?
After examining the potential maps for LiH, HF and answer the following question:
Which compound has the hydrogen that would be most apt to attract a negatively charged molecule?
Estimate the pKa values of the following compounds.
(a)CH3CH2CH2NH2
(b)CH3CH2CH2OH
(c)CH3CH2COOH
(d)CH3CH2CH2NH3+
You are planning to carry out a reaction that produces protons. The reaction will be buffered at pH = 10.5. Would it be better to use a protonated methylamine/methylamine buffer or a protonated ethylamine/ethylamine buffer? (pKa of protonated methylamine = 10.7; pKaof protonated ethylamine = 11.0)
Which is the stronger acid?
a. CH3CH3 or HC ≡CH
b. H2C= CH2or HC≡ CH
c. H2C =CH2 or CH3CH3
