Chapter 7: PROBLEM 7.48 (page 291)

Question: Rank the species in each group in order of increasing leaving group ability.

a. Br-,Cl-,I-

b. NH3,H2S,H2O

Short Answer

Expert verified

Answer

a. Cl-< Br-<I-

b. NH3 < H2O <H2S

Step by step solution

01

Leaving group ability

When the size of the leaving group atom increases, it attains stable and independent existence.

Another measure to identify the better leaving group is its pKavalue.

Lesser the value of pKa , the greater the ability it has to act as a leaving group.

02

The given molecules

a. In this set of ions, the size of I-is the largest and next Br-is larger than Cl-.

Thus, the leaving group ability is as shown below:

Cl-< Br-< I-

b. The values of the given compounds are as follows:

NH3 35

H2O 15.7

H2S 7

The best leaving group is the one that has less pKa (acid dissociation constant) value, The order is shown below:

NH3< H2O < H2S
