Question: 8.2

Acid/Base Pairs . For each acid–base equilibrium, label the stronger acid, the stronger base, the weaker acid, and the weaker base. Then predict whether the position of equilibrium lies toward the right or toward the left.

Verified Answer:

Use Table 8.2 to identify the stronger acid from t...

Question: 12.5

\Drawing Alkene Cis-Trans Isomers Draw all stereoisomers that are possible for the following unsaturated alcohol. Strategy To show cis-trans isomerism, each carbon of the double bond must have two different groups bonded to it. If a molecule has n double bonds about which cis-trans isomerism is

Verified Answer:

Cis-trans isomerism is possible only about the dou...

Question: 8.4

Acid Strength Which is the stronger acid: (a) Benzoic acid with a Ka of 6.5 * 10^-5 or hydrocyanic acid with a Ka of 4.9 * 10^-10? (b) Boric acid with a pKa of 9.14 or carbonic acid with a pKa of 6.37? Strategy Relative acid strength is determined by comparing the Ka values or the pKa values. If
