Which of the following compounds has the highest boiling point? CH4, CH3CH2CH2CH2OH CH3SOCH3, CH3CH2CH2CH2OH CH3OCH2CH(CH3)2 CH3CH2OCH2CH2CH3 Which of the following compounds should be the most water soluble? OH CH3<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n
Part 1: Compound with the Highest Boiling Point<\/strong><\/h3>\n\n\n\n
Boiling point depends on intermolecular forces. The stronger the forces, the more energy is needed to separate the molecules, and the higher the boiling point.<\/p>\n\n\n\n
\n
CH\u2084<\/strong> has only London dispersion forces. It is nonpolar and has the lowest boiling point.<\/li>\n\n\n\n
CH\u2083CH\u2082CH\u2082CH\u2082OH<\/strong> (butanol) is a straight-chain alcohol and exhibits strong hydrogen bonding, dipole-dipole forces, and London forces.<\/li>\n\n\n\n
CH\u2083SOCH\u2083<\/strong> (dimethyl sulfoxide or DMSO) has strong dipole-dipole interactions due to the highly polar S=O bond but does not form hydrogen bonds as strong as those in alcohols.<\/li>\n\n\n\n
CH\u2083OCH\u2082CH(CH\u2083)\u2082<\/strong> and CH\u2083CH\u2082OCH\u2082CH\u2082CH\u2083<\/strong> are ethers. Ethers cannot hydrogen bond to themselves and thus have weaker intermolecular forces than alcohols.<\/li>\n\n\n\n
Therefore, CH\u2083CH\u2082CH\u2082CH\u2082OH<\/strong> has the highest boiling point due to strong hydrogen bonding<\/strong> and a relatively larger surface area.<\/li>\n<\/ul>\n\n\n\n\n\n\n\n
Part 2: Most Water-Soluble Compound<\/strong><\/h3>\n\n\n\n
Given:<\/strong> A compound with \u2013OH<\/strong> and CH\u2083<\/strong> groups<\/p>\n\n\n\n
Correct Answer:<\/strong> The compound with an \u2013OH (hydroxyl) group<\/strong><\/p>\n\n\n\n
Explanation:<\/strong><\/p>\n\n\n\n
Water solubility depends on a molecule’s ability to hydrogen bond with water. The \u2013OH<\/strong> group is highly polar and can form strong hydrogen bonds with water, making such compounds highly water soluble.<\/p>\n\n\n\n
\n
A CH\u2083<\/strong> group is nonpolar and hydrophobic. It does not hydrogen bond well with water and thus contributes little to solubility.<\/li>\n\n\n\n
A molecule like methanol (CH\u2083OH)<\/strong> is water soluble due to the presence of the hydroxyl group.<\/li>\n\n\n\n
Therefore, among choices with either OH<\/strong> or CH\u2083<\/strong>, the one with \u2013OH<\/strong> is significantly more water soluble.<\/li>\n<\/ul>\n\n\n\n<\/figure>\n","protected":false},"excerpt":{"rendered":"
