- You will not find “hydroxide” in the stockroom, but you will find sodium hydroxide (NaOH) andpotassium hydroxide (KOH). Lithium hydroxide (LiOH) is expensive and used in spacecraft airfilters since hydroxide reacts with carbon dioxide, and lithium is lighter than sodium or potassium.Cesium and francium hydroxides are very expensive and little used. Is this information consistentwith your answer to the previous question?arrow_forwardDraw Lewis Structures for the following compounds. (Be sure to minimize formal charges and draw resonance structures where appropriate.): XeF2O, ClO4-, HNO2, CH3CH(NH2)COOH (amino acid alanine). Identify the molecules with the following labels (1 is more than one label): Oxyacid, has a resonance structure, expanded octet, has a carbon backbone For the molecule with resonance structures—what is the bond order for the atoms that share e-?arrow_forwardDefine the relation between Bonding Models and AIDS Drugs ?arrow_forward
- I'm confused by the (CH3)2 at the final step. is there supposed to be a - connecting it? What is the name of the molecule? I've never seen a structure written like thatarrow_forwardHigh oil and gasoline prices have renewed interest in alternative methods of producing energy, including the “clean” burning of coal. Part ofwhat makes “dirty” coal dirty is its high sulfur content. Burning dirty coal produces sulfur dioxide (SO2), among other pollutants. Sulfurdioxide is oxidized in the atmosphere to form sulfur trioxide (SO3), which subsequently combines with water to produce sulfuric acid—amajor component of acid rain. Draw all possible resonance structures of sulfur trioxide.arrow_forwardLinoleic acid is an essential fatty acid found in many veg-etable oils, such as soy, peanut, and cottonseed. A key structural feature of the molecule is the c is orientation around its two dou-ble bonds, where R1and R2 represent two different groups thatform the rest of the molecule. (a) How many different compounds are possible, changing onlythe cis-trans arrangements around these two double bonds?(b) How many are possible for a similar compound with three double bonds?arrow_forward
- 1. What is resonance contributor in which one or more atoms bears a formal change and the most stable resonance form? 2.what is the process of distributing electron pairs in a molecule? 3. Are organic molecules which are less sterically hindered more attractive than those which are more sterically hindered?arrow_forwardRank BF3, BF2H, and BFH2 from least polar to most polar.arrow_forwardThe carbon–carbon bond length in C2H2 is 1.20 Å, that inC2H4 is 1.34 Å, and that in C2H6 is 1.53 Å. Near which ofthese values would you predict the bond length of C2 tolie? Is the experimentally observed value, 1.31 Å, consistent with your prediction?arrow_forward
- Sketch the hydrogen bond(s) that form between ethanol and nitrogen trihydride and dihydrogen monoxide. Show the proper VSEPR shapes of all molecules (meaning VSEPR shapes with proper bond angles) and use dotted or dashed lines to indicate the hydrogen bonds. Indicate 4 different H-bonds between: 1) ethanol and nitrogen trihydride 2) ethanol and dihydrogen monoxide 3) dihydrogen monoxide and nitrogen trihydride and then 4) between the two ethanol molecules.arrow_forwardCarboxylic acid functional groups can be part of the parent chain of a molecule. This means that the carbon atom in the functional group is also part of the main carbon chain. However, carboxylic acid functional groups can also branch off the main chain. The following example contains both types of carboxylic acid functional groups. Draw the structure in bond-line notation. HOOCCH2CH(COOH)CH2COOHarrow_forwardOrganic chemistry HW A 3D representation of a cyclohexane (C6H12) molecule, a cyclic compound used in the manufacture of nylon and found in the distillation of petroleum, is shown. Name the geometry around each carbon atom.arrow_forward
