Question

Which of the following has least solubility?

• A. n-Butyl alcohol
• B. sec-Butyl alcohol
• C. tert-Butyl alcohol
• D. All have same

Answer 1

The correct option is A

n-Butyl alcohol

As we saw in the videos,

Decreasing solubility order in $H_{2}O$.

t-Butyl alcohol $>$ sec-Butyl alcohol $>$ n-Butyl alcohol $(3>2>1)$.

Lesser the surface area, greater is the solubility in $H_{2}O$. Hence, the solubility order is as given above.
