Interpretation:
The products that would be formed on salicin reacting with dilute aqueous HCl is to be determined and the mechanism of reaction for the this reaction is to be outlined.
Concept introduction:
舧 Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles, which accept electron pair.
舧 Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles, which donate electron pair.
舧 Substitution reaction: A reaction in which one of the hydrogen atoms of a hydrocarbon or a
舧 Elimination reaction: A reaction in which two substituent groups are detached and a double bond is formed is called elimination reaction.
舧 Addition reaction: It is the reaction in which unsaturated bonds are converted to saturated molecules by the addition of molecules.
舧 A carbohydrate is a
舧 Salicin is a naturally occurring glycoside and is originally found in the bark of willow trees. It is an effective analgesic for relieving pain. Its structure is given below:
舧 Glycosides are carbohydrate acetals and can be simple or complex. These molecules are stable in basic solutions, but produce sugar and alcohol in acidic solutions.

- (a) Isoleucine has been prepared by the following sequence of reactions. Give the structure of compounds A through D isolated as intermediates in this synthesis.(b) An analogous procedure has been used to prepare phenylalanine. What alkyl halide would you choose as the starting material for this synthesis?arrow_forwardSynthesize octadecyl stearate using linoleic acid (18:2) (Given, stearic acid: 18:0) as the only starting material.arrow_forward22.47 Tertiary amines with three different alkyl groups are chiral but cannot be resolved because pyramidal inversion causes racemization at room temperature. Nevertheless, chiral aziridines can be resolved and stored at room temperature. Aziridine is a three-membered heterocycle containing a nitrogen atom. The following is an example of a chiral aziridine. In this compound, the nitrogen atom is a chiral center. Suggest a reason why chiral aziridines do not undergo racemization at room temperature.arrow_forward

- Provide the correct structure from the IUPAC name. (a) 2-aminocyclopropanecarboxylic acid (b) 3-mercapto-5-oxoheptanal (c) Propyl 2,2,4-trimethyloct-4-enoate (d) 4-oxocycloheptanecarbaldehyde (e) N,N,4,4-tetraethylhexanamide (f) Acetic pentanoic anhydride (g) Acetyl chloride (h) Methyl 3,3-diethyl-6-octynoatearrow_forwardGive reasons: (i) Bond length of C = O in carboxylic acids is slightly larger than C = O bond length in carbonyl compounds. (ii) There are two –NH2 groups in semicarbazide. However, only one –NH2 group is involved in the formation of semicarbazones. (iii) Benzoic acid is less soluble in water than acetic acid. (iv) Formic acid is a stronger acid than acetic acid.arrow_forwardDraw the structures of the following.arrow_forward
