Alcohols are weaker acids than carboxylic acids because: the anion in the conjugate base of the alcohol is delocalised the anion in the conjugate base of the alcohol is localised the O-H group in the alcohol will undergo hydrogen bonding the O-H group in the alcohol will not undergo hydrogen bonding

Which of the following statements is NOT true about phenol? Select the correct answer below: The aromatic ring delocalizes and stabilizes the negative charge on the oxygen in the phenoxide ion. Therefore, phenols completely dissociate in water. A phenol will generally form stronger hydrogen bonds than nonaromatic alcohols because the oxygen-hydrogen dipole in the hydroxyl group is stabilized by resonance from the aromatic ring. The phenol functional group is a weak acid in water because the hydroxyl group dissociates slightly....

Unsaturated fatty acids have lower melting points than saturated fatty acids because A. they have fewer hydrogen atoms B. They have more hydrogen atoms C. their molecules fit closely together D. the cis double bonds give them an irregular shape E. the trans double bonds give them an irregular shape

In methyl mercaptan (CH3SH), the C-H bond is smaller than the S-H bond. Why? A. Because sulfur has a smaller bonding atomic radius than carbon B.Because hydrogen has a smaller bonding atomic radius than sulfur C. Because hydrogen has a smaller bonding atomic radius than carbon D. Because carbon has a smaller bonding atomic radius than sulfur E. Because carbon has a smaller bonding atomic radius than hydrogen

123. Which of the following statements is/are true? I. Because ionic forces are so much stronger than hydrogen bonds, no ionic compound will be soluble in ethanol (CH3CH2OH) II. Making of any solution in which a solid is dissolved in a liquid will always have a positive entropy. III. the heats of hydration of ions increase (become more exothermic) as ionic charge increases a. I and II only b. I and III only c. II and III only d. all...

These two molecules have an identical number of electrons. However, the boiling point of Compound B is much higher than that of Compound A How does chemistry rationalizelexplain this difference? CH3CH2CH2-NH2 (A) boiling pt = : 48 °C CH3CH2CH2-OH (B) boiling pt = 98°C Select one: O Compound B exhibits hydrogen-bonding forces, but Compound A does not exhibit hydrogen-bonding forces O Compound B exhibits hydrogen bonding forces but it is hydrophobic, so it does not boil easily. Because O-H is...
