Interpretation:
A reasonable explanation is to be provided for each of the listed observations.
Concept introduction:
Boiling point of a compound depends on the strength of intermolecular forces between its molecules. Stronger the intermolecular forces, higher the boiling point.
The strength of different types of intermolecular forces in covalent compounds varies as
Addition to a planar
Quaternary ammonium hydoxides undergo
Primary
Primary carbocation can undergo rearrangement if it results in a more stable secondary or tertiary carbocation.

- Predict the major products formed when benzoyl chloride (PhCOCl) reacts with the following reagents.(a) ethanol (b) sodium acetate (c) anilinearrow_forwardGive the chemical tests to distinguish between following pair of compounds : (i) Propanol and propanone (ii) Ethyl acetate and methyl acetate (iii) Benzaldehyde and benzoic acid (iv) Benzaldehyde and acetaldehyde (v) Formic acid and acetic acid (vi) Propanal and propanol (vii) Ethanoic acid and ethylethanoatearrow_forwardNitroxoline is the generic name by which 5-nitro-8-hydroxyquinoline is sold as an antibacterial drug. Write its structural formula.arrow_forward
- Write 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_forward(ii) Describe the key molecular structure features of the pharmacologically active 2- oxazolidinone group of antibacterial agents.arrow_forward(a) Draw the three isomers of benzenedicarboxylic acid.(b) The isomers have melting points of 210 °C, 343 °C, and 427 °C. Nitration of the isomers at all possible positions was once used to determine their structures. The isomer that melts at 210 °C gives two mononitro isomers. The isomer that melts at 343 °C gives three mononitro isomers. The isomer that melts at 427 °C gives only one mononitro isomer. Show which isomer has which melting point.arrow_forward
- Predict the products from the reactions of the following amines with sodium nitrite indilute HCl.(a) cyclohexanaminearrow_forwardWrite an equation for the acid-base equilibrium of:(a) Pyrrolidine and water (b) Pyridine and waterarrow_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_forwardWrite chemical equations expressing each of the following: (a) Preparation of o-nitrophenyl acetate by sulfuric acid catalysis of the reaction between a phenol and an acid anhydride. (b) Esterification of 2-naphthol with acetic anhydride in aqueous sodium hydroxide (c) Reaction of phenol with benzoyl chloridearrow_forward4-chlorophenol has a pka of 9.41 and diethylmethylamine has a pkb of 3.65. A 1.0M solution of diethylmethylammonium-4-chlorophenolate would be strongly acidic neutral weakly acidic weakly basic strongly basicarrow_forward
