Question

Alcohols are substances with polar properties, allowing solutions of alcohols in water.
Which of the following alcohols compounds is the least soluble in water?

• A. $C{H}_{3}OH$
• B. $C{H}_{3}C{H}_{2}OH$
• C. $C{H}_{3}C{H}_{2}C{H}_{2}OH$
• D. $C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}OH$

Answer 1

Answer: (D)

$C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}OH$

${CH}_3-{CH}_2-{CH}_2-{CH}_2-OH$ because of its largest alkyl group, it forms the largest positive ion as a result its solubility is the least.
