Which of the following statement(s) about 2 methyl 1 propanol, (CH_3)_2CHCH_2OH,

Question

Which of the following statement(s) about 2 methyl 1 propanol, (CH_3)_2CHCH_2OH, and propylene glycol, CH_3CHOHCH_2OH are true? 2-Methyl-1-propanol is more soluble in water than is propylene glycol because 2-methyl-1 -propanol has a smaller molecular mass. Propylene glycol is more soluble in water than is 2-methyl-1 -propanol because propylene glycol has a smaller molecular mass 2-Methyl-1-propanol is more soluble in water than is propylene glycol because 2-methyl-1 -propanol forms fewer hydrogen bonds with water. Propylene glycol is more soluble in water than is 2-methyl-1-propanol because propylene glycol can form multiple hydrogen bonds with water.

Explanation / Answer

Due to presence of 2 -OH groups propylene glycol(molecular weight =76) is more soluble (form more hydrogen bonding with water) rather miscible than 2-Methyl -1-propanol (molecular weight = 74)(8.7 ml /100 ml water).

The last statement is correct.
