Question 1 Choose all of the following characteristics of Hydrogen bonds. 1. N-H is a donor 2. Occurs with hydrogen functional groups. 3. Many are required to form a stable interaction between molecules 4. A water molecule can be a donor but not an acceptor 5. Are a type of weak bond 6. C_H is a donor 7. Can form with carbon as a acceptor Force of attraction between atoms of a molecule 8. Question 2 Which of the following are characteristics of hydrophobic interactions (choose all that apply) 1. 2. 3. 4. 5. Are weak bonds Form without water Occur with hydrocarbon functional groups Cannot occur with amphipathic molecules Can stabilize the interaction between two protein molecules that have non-polar functional groups Exclude water from interior of bilayer membranes 6. Questioin 3 1. 2. 3. 4. Stability depends on the number of interactions that form Must be mediated by a force of attraction Can produce highly ordered structures Can stabilize an interactions between two protein molecules Question 4 Which of the following is the reason that C H cannot serve as a donor for a hydrogen bond? 1. Aggregates in water 2. 3. 4. Question 5 Lacks a temporary dipole Lacks a permanent charge Lacks a permanent dipole Choose all of the following that are properties of bulk water 1. 2. 3. 4. Accounts for Van Der Waals forces Causes hydrophobic interactions to form Causes dipoles to form Stabilizes bonds between strands of DNA Question 6 Solution 1 . - NH is a donor. - occurs with hydrogen functional group. -many are required to make a stable interaction b/w the molecules. -are a type of weak bond. - force of attraction b/w atoms of a molecule . .
