Methanol not soluble in hexane, but heptanol is soluble. Why? Look up the structures and determine the intermolecular forces for all three molecules. The larger alcohol (heptanol) has larger nonpolar, hydrophobic regions in addition to its hydrophilic hydroxyl group $(\mathrm{OH})$. The larger nonpolar regions of heptanol interact with hexane via dispersion forces to be soluble than the smaller alcohol (methnaol). The larger alcohol (heptanol) has a smaller nonpolar, hydrophobic regions in addition to its hydrophilic hydroxyl group $(\mathrm{OH})$. The smaller nonpolar regions of heptanol interact with hexane via dispersion forces to be soluble than the larger alcohol (methnaol). The larger alcohol (heptanol) has larger nonpolar, hydrophobic regions in addition to its hydrophilic hydroxyl group $(\mathrm{OH})$. The larger nonpolar regions of heptanol interact with hexane via hydrogen bond to be soluble than the smaller alcohol (methnaol).
