Interpretation: The
Concept introduction: Functional groups are specific substituents present in the molecule that is responsible for the characteristic
(b)
Interpretation: The site at which pantothenic acid can form hydrogen bond to water molecule is to be predicted.
Concept introduction: Hydrogen bonding is the strongest intermolecular forces present between the substances. A hydrogen atom participates in hydrogen bonding if it is bonded to an electronegative atom like fluorine, oxygen or nitrogen.
(c)
Interpretation: The solubility of pantothenic acid in water is to be predicted.
Concept introduction: The general rule of solubility is like dissolves like, in other words, polar compounds dissolve in polar solvents, and non-polar compounds dissolve in non-polar solvents.
The polar solvent such as water has partial

- (a) Draw the structures for the eight constitutional isomers of molecular formula C 4H 11N. (b) Give the systematic name for each amine. (c) Identify the chirality center present in one of the amines.arrow_forwardTRUE OR FALSE (a) There are three amines with the molecular formula C3H9N. (b) Aldehydes, ketones, carboxylic acids, and esters all contain a carbonyl group. (c) A compound with the molecular formula of C3H6O may be either an aldehyde, a ketone, or a carboxylic acid. (d) Bond angles about the carbonyl carbon of an aldehyde, a ketone, a carboxylic acid, and an ester are all approximately 109.5°. (e) The molecular formula of the smallest aldehyde is C3H6O, and that of the smallest ketone is also C3H6O. (f) The molecular formula of the smallest carboxylic acid is C2H4O2.arrow_forwardDraw the structural formulas of the following compounds:(a) 2,3-Dimethylpentanal(b) 1,3-Dibromopropanone(c) 4-hydroxy-4-methylhexan-2-onearrow_forward
- In each of the following reactions, two possible organic products can be formed. Draw both organic products in each case and then circle the one formed in greatest quantity in each case. HC (a) 1) NaH, 2) acid (b) CH,CH,OH (c) CH,CH,OH NH2 (d) Oarrow_forwardBile salts are derivative of cholestrol. However, the solubilities of these compounds in water are drastically different; cholestrol is highly hydrophobic, and the bile salts are soluble in digestive juices. Explain the differences.arrow_forwardIndicate whether each statement is true or false: (a) Fat molecules contain amide bonds. (b) Phosphoplipids can be zwitterions. (c) Phospholipids form bilayers in water in order to have their long hydrophobic tails interact favorably with each other, leaving their polar heads to the aqueous environment.arrow_forward
- Certain omega-3 fatty acids can be found only in animal sources, such as fatty fish. Two of these are eicosapentaenoic acid (EPA) [20:5] and docosahexaenoic acid (DHA) [22:6], both of which are ω-3 fatty acids. DHA has been shown to be important in healthy brain development, so it has recently been added to infant formulas. Breast milk is rich in DHA as long as the mother maintains a healthy diet that includes fish. Draw skeletal structures of the fatty acids EPA and DHA.arrow_forwardAlkaloids are basic nitrogen-containing compounds of plant origin, many of which are physiologically active when administered to humans. Ingestion of coniine, isolated from water hemlock, can cause weakness, labored respiration, paralysis, and eventually death. Coniine is the toxic substance in the “poison hemlock” used in the death of Socrates. In small doses, nicotine is an addictive stimulant. In larger doses, it causes depression, nausea, and vomiting. In still larger doses, it is a deadly poison. Solutions of nicotine in water are used as insecticides. Cocaine is a central nervous system stimulant obtained from the leaves of the coca plant.Classify each amino group in these alkaloids according to type (primary, secondary, tertiary, aliphatic, aromatic, heterocyclic).arrow_forwardWhat products are formed when benzoic acid (C 6H 5COOH) is treated with each base: (a) NaOH; (b) Na 2CO 3; (c) NaHCO 3?arrow_forward
- (a) Draw a skeletal structure of the anabolic steroid 4-androstene-3,17-dione, also called "andro," from the following description. Andro contains the tetracyclic steroid skeieton with carbonyl groups at C3 and C17, a double bond between C4 and C5, and methyl groups bonded to C10 and C13. (b) Add wedges and dashes for all stereogenic centers with the following information: the configuration at C10 is R, the configuration at C13 is S, and all substituents at ring fusions are trans to each other.arrow_forward4 But-2-enal, CH₂CH=CHCHO, is a pale yellow, flammable liquid with an irritating odour. (a) But-2-enal exists as two stereoisomers. Draw skeletal formulae to show the structure of the two stereoisomers of but-2-enal. (b) (i) Describe a simple chemical test that would show that but-2-enal is an aldehyde. (ii) Explain why this test gives a different result with aldehydes than it does with keton (c) But-2-enal also reacts with sodium borohydride, NaBH4. (i) Identify the organic compound formed in this reaction. (ii) State the type of chemical reaction occurring. (d) Precautions must be taken to prevent but-2-enal catching fire. Construct a balanced equation for the complete combustion of but-2-enal, C₂HO.arrow_forwardWrite the reagent or draw structures of the starting material or organic product(s) in the following reactions. If more than one product is formed, identify the major product where possible. (a) (b) HO OH OH H2SO4 ? Cl₂ ? FeCl3arrow_forward
