Compare diethyl ether (CH;CH2OCH2CH3) and pentane (CH3CH2CH2CH2CH3). Identify which structure is more polar and the reason for this difference. A) Diethyl ether is more soluble because it has a permanent dipole. B) Diethyl ether is more soluble because it has shorter carbon chains. C) These comp nds are equally soluble in water. D) Pentane is more soluble because it does not have a permanent dipole. E) Pentane is more soluble because it has a longer carbon chain.

The boiling points of 2-hexanol and 1,5-pentanediol are 140 °C and 250 °C, respectively. Choose the BEST explanation for the observation that 1,5- pentanediol has a higher boiling point than 2-hexanol. A) 1,5-Pentanediol has a higher molecular weight, which increases intermolecular attractions. B) 1,5-Pentanediol has two alcohol groups for hydrogen bonding, which increases intermolecular attractions. C) 1,5-Pentanediol has 1° alcohols, which increases intermolecular attractions. D) 1,5-Pentanediol has less branching, which increases surface area and intermolecular attractions.
