Greater the number of hydroxyl groups, greater the solubility in water. Between (II) and (III), (III) is slightly less soluble due to greater hydrophobic alkyl fraction.

Q. What is the increasing order of solubility of the following in water?
$C H_{3} O H (I), H OC H_{2} C H_{2} O H (II), C H_{3} — C H (O H) — C H_{2} O H$
$(III), H OC H_{2} — O H ∣ C H — C H_{2} O H (I V)$

$I < II < III < I V$

$I V < III < II < I$

$I < III < II < I V$

$I V < II < III < I$
