Niall G. Howlen, PhD. BCH311.Spming 201 8. For a spontancous reaction which of the following is generlly true b) AS- c) AS> 9. The hydrolysis of ATP involves a large release of energy because: a A b) phosphoric acid anhydride bond is broken A phosphoric ester bond is broken c) d) The -D-ribose sugar of ATP is made up of high-energy bonds The purine base adenine is made up of high-energy bonds e) All of the above 10. The heat of vaporization of HO is 2.260 Jig while that of CH,(CH.,CH, (butane) is 381 J/g. The primary reason vaporization for this large difference is the ability of H,O molecules to: a) readily dissociate into H' and OH b) form hydrogen bonds with H,O c) form ionic bonds with H,C readily dissociate into H,O' and OH form covalent bonds with H,O d) e) 1. Which of the following bonds is most non polar? r HC a) O-H b) N-H c) C-H d) c-O e) O-P C1-Cl hare tnu same elechon Ethanol (C,H,OH) is readily soluble in H,0 because of which of the following interactions? a) Ion-dipole interactions b) Covalent interactions Hydrogan bonding= poll Dipole

Explanation / Answer

Option B, since during the hydrolysis of ATP to ADP and Pi. During this P-O bond is broken and new P-O bond formed. Newly formed bonds are stronger. Hence more energy released.

10. Option B since water forms Hydrogen bonds, hence it needs more energy to evaporate while alkanes won't form Hydrogen bonds. Hence little energy is sufficient to evaporate.
