- Draw the structure of each of the following molecules. (a) 5-phenylpentanamide; (b) (2S,3S)-2,3-dimethoxyhexanediamide; (c) N-phenylcyclobutanecarboxamidearrow_forwardWrite a structural formula for each of the following compounds: (a) m-Chlorobenzoyl chloride (b) Trifluoroacetic anhydride (c) cis-1,2-Cyclopropanedicarboxylic anhydride (d) Ethyl cycloheptanecarboxylate (e) 1-Phenylethyl acetate (f) 2-Phenylethyl acetate (g) p-Ethylbenzamide (h) N-Ethylbenzamide (i) 2-Methylhexanenitrilearrow_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_forward
- The odor of ripe bananas and many other fruits is due to the presence of esters. For example: Banana oil (isopentyl acetate) (a) Write the name (common or IUPAC) of the ester responsible for the fragrance of the following: pineapple, orange, apple, peach, & lavender (b) Choose one fragrant from (a) and name the alcohol and the carboxylic acid needed to synthesize this ester. (c) Show the detailed mechanism of the Fischer Esterification reaction that will be involved in the synthesis of the fragrant you have chosen in part (a).arrow_forwardcomplete the reactiona and draw it outarrow_forward(a) Account for the following :(i) Cl – CH2COOH is a stronger acid than CH3COOH.(ii) Carboxylic acids do not give reactions of carbonyl group.(b) Write the chemical equations to illustrate the following name reactions:(i) Rosenmund reduction (ii) Cannizzaro’s reaction(c) Out of CH3CH2 – CO – CH2 – CH3 and CH3CH2 – CH2 – CO – CH3, which gives iodoform test?arrow_forward

(b) Suggest three (3) different Grignard reactions leading to 2-phenyl-2-butanol.arrow_forwardAnswer ALL parts of this question. (a) Provide the structure and name of the aldehyde with the formula, C2H4O. (b) Draw the two steps of the Strecker synthesis used for the conversion of the aldehyde in part (a) into racemic alanine. (c) Draw the (R) and (S) enantiomers of alanine. Which is the naturally occurring enantiomer? (d) Draw the structure of the dipeptide, Ala-Gly.arrow_forward
- Give the expected organic product when phenylacetic acid, PhCH2COOH, is treated with reagent Q.)NaHCO3, H2Oarrow_forwardWhich is least reactive in electrophilic aromatic substitution? (A) (B) CH3 (C) CHO (D) C3arrow_forwardHypoglycin A, an amino acid derivative found in unripened lychee, is anacutely toxic compound that produces seizures, coma, and sometimesdeath in undernourished children when ingested on an empty stomach. (a) Draw the neutral, positively charged, and negatively charged forms of hypoglycin A. (b) Which form predominates at pH = 1, 6, and 11? (c) What is the structure of hypoclycin A at its isoelectric point?arrow_forward
