Explanation / Answer

The compound (cpd) is consider as soluble in any solvent if it dissolves to the extent of about 3 % .

Compounds soluble in ether

• Non ionic • Contain five or less carbon atoms

• Contain an active group that is polar

Compounds insoluble in ether

• Ionic .

• Contain two or more polar groups with no more than four carbon atoms per each polar group

This group is classified as S2 class and includes ionic salts such as salts of carboxylic acids and amines and compounds with more than one active group such as polyhydroxylated compounds and carbohydrates

Therefore all the compounds listed will be soluble in ether

•Contain only one strong polar group
