- The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)arrow_forwardIn an ammonia molecule, one nitrogen atom (atomic number = 7; 1s² 2s²2p³) forms covalent bonds with three hydrogen atoms. Draw a diagram of an ammonia molecule. Show all valence electrons, lone pairs, molecular geometry, and partial charges (assume sp³ hybridization).arrow_forwardWhich of these statements about the tertiary structure of a polypeptide is(are) untrue? You may select more than one answer. The tertiary structure will be maintained when the solvent is changed from pure water to aqueous acetic acid. O The tertiary structure is determined in part by the formation of disulfide bridges. Hydrogen bonding interactions are responsible for formation of secondary structure but not tertiary structure, O The tertiary structure is rigid and unchanging. O Charge-charge (electrostatic) interactions can be important in the tertiary structure.arrow_forward
- :0-H-1--:N-H Hydrogen Bond Which statement best helps explain the formation of the hydrogen bond represented in the figure? A The oxygen has a partial positive charge, and the nitrogen has a partial negative charge. (B) The nitrogen has a partial negative charge, and the hydrogen attached to the oxygen has a partial positive charge.arrow_forwardExercise A: Amino Acid Functional Groups Figure 1 below shows one of the 20 amino acids that make up proteins. Recall that carbon can form four covalent bonds. Amino acids consist of a central carbon, called the a-carbon, that is bonded to four different chemical groups. H + CH2 OH Figure 1. Structure of an amino acid Answer the below questions in your own document. • On the amino acid shown in Figure 1, label the a-carbon. • The a-carbon of each of the 20 amino acids is bonded to one hydrogen atom, one amino group, one carboxyl group, and one R group (more on that below). You should recognize the amino and carboxyl groups from our discussion of functional groups in organic molecules. Circle and label* the amino group and the carboxyl group in Figure 1. *Note: our goal in this question, and in similar questions throughout this lab, is for you to be able to identify specific structures. You can do this circling/labeling in whatever way is easiest for you. You might want to draw the…arrow_forwardWhat are the names of the seven functional groups found in organic molecules?

- The figure below illustrates the molecular structures of two fatty acids. A B H₂C The structural formula of erucic acid and behenic acid с H₂C D erucic acid behenic acid Which of the following best explains why erucic acid is liquid at room temperature but behenic acid is solid at room temperature? O OH The presence of a double carbon to carbon bond in erucic acid prevents the molecule from packing closely together. The lack of any double carbon-carbon bonds in behenic acid causes the molecule to be come polar and therefore packed more tightly. The larger number of carbon atoms in erucic acid prevents the molecule from packing tightly together. OH The smaller number of carbon atoms in behenic acid creates stronger covalent bonds between the carbon atoms allowing for them to pack more tightly together.arrow_forwardSuppose you had an organic molecule such as cysteine (see Figure 4.9,sulfhydryl group example), and you chemically removed the --NH2 group and replaced it with --COOH. Draw this structure. How would this change the chemical properties of the molecule? Is the central carbon asymmetric before the change? After?arrow_forwardwhich of the bonds in the molecule below are polar. explain why.arrow_forward
- Which of the following explains why methyl anion has a pyramidal geometry while methyl cation is planar? The HOMO energy decreases upon pyramidalization of the anion but increases for the cation Hyperconjugation stabilizes the planar cation Selected Steric repulsion between the H atoms disfavors the pyramidal anion All of the orbitals for the pyramidal structure are lower energyarrow_forwardC8H17NO2 is heated, and a condensation reaction occurs. A new molecule containing one peptide bond is formed and has the molecular formula C8H15NO. Draw the skeletal structure of this new compound.arrow_forwardThe carbohydrates (CHOs), with a general formula of (CH₂O)n, are rich in hydroxyl groups. This allows the carbohydrates incredibly diversity of structure and function. Match the structural feature with the functional feature allowed. CHOs are useful for fast energy production. CHOs are widely used to mediate molecular recognition events. CHOS are widely used as structural materials. 1. 2. 3. Hydroxyl groups can interact extremely well with water. Hydroxyl groups can be extensively derivatized and functionalized. Hydroxyl groups allow CHOs to form extensive H-bonded networks.arrow_forward
