13. The conjugate acid of methylamine ( CH3NH2) is- A) *CHẠNH B) CH3NH3 C) CH3NH2* B) CH3NH2 E) CH3NH3+ 14. Which one of the following is the weakest acid? A) CH3C=CH B) CH3CH2CH2OH C) CH3CH2COOH D) CH3CH2CH2SH E) CF3CH2COOH

For the previous four questions, label each molecule that appears in the question or your answer asstrong acid, strong base, weak acid, or weak base.

As we shall see in Chapter 19, hydrogens on a carbon adjacent to a carbonyl group are far more acidic than those not adjacent to a carbonyl group. The anion derived from acetone, for example, is more stable than is the anion derived from ethane. Account for the greater stability of the anion from acetone.

Use Table 13-2 to order the following from the strongest to the weakest acid. HClO2,H2O,NH4+,HClO4

A very strong base can remove a proton from methylamine:

Label each molecule according to increasing acidity with 1 as the weakest and 4 as the strongest based on their structure. Explain.

Describe the acidity/basicity of each species and estimate the position of each equilibrium. CH3CH₂O + CH3C=CH CH3CH₂OH + H3CC=C b d a On the left, a is the and b is th✓ On the right, c is the and d is tl The species favored at equilibrium are those stronger acid stronger base weaker acid weaker base C C
