(A) Group I Cations Are Common Ions Found in Organic

Short Answer

(a) Group I cations are common ions found in organic salts.Write the electron configuration for the Group I cations below.In the fourth column,use circles to represent the relative size of each cation conceptually.Define the term ionic radius and label the ionic radius of each cation.

(b) Organic molecules called crown ethers (refer to the box titled "Phase Transfer Catalysts" in Chapter 2 of your text)can sequester a cation of specific size to make the organic anion more reactive.Charles Pedersen,in fact,shared the 1987 Nobel Prize in Chemistry for contributions to the synthesis of crown ethers.Suppose you wanted to use a crown ether to selectively remove each individual cation from a solution of sodium,lithium,and potassium.For each cation,which crown ether might you add?
