(a)
Interpretation:
Reagents and experimental conditions by which an oxanamide can synthesized from butanal has to be shown.
Concept introduction:
Acid chlorides are most often prepared by treating a
Alkyl or aryl magnesium halides (RMgX) are known as Grignard reagent. The Grignard reaction is an organometallic
Reaction of Grignard reagent with a formic ester followed by hydrolysis in aqueous acid yields secondary alcohol. Tertiary alcohol can be prepared by the reaction of Grignard reagent with ester other than formate.
(b)
Interpretation:
The number of chiral centers and stereoisomers possible for the given compound has to be shown.
Concept introduction:
Chiral centre:
A chiral centre is defined as the tetrahedral carbon atom in an organic molecule that is connected to four non-identical groups/substituents. It is sometimes known as a stereo genic centre.
Stereoisomers: Two compounds with same molecular formula but different in their orientation are considered as isomers.
Number of possible stereoisomers for a compound can be determined as,

- Predict the major products formed when benzoyl chloride (PhCOCl) reacts with the following reagents.(a) ethanoarrow_forwardAn unknown compound A of molecular formula C10H18O reacts with H2SO4 to form two compounds (B and C)of molecular formula C10H16. B and C both react with H2 in the presence of Pd-C to form decalin. Ozonolysis of B forms D, and ozonolysis of C forms a diketone E of molecular formula C10H16O2. Identify the structures of compounds A, B, C, and E.arrow_forward(a) How will you convert:(i) Benzene to acetophenone (ii) Propanone to 2-Methylpropan-2-ol(b) Give reasons :(i) Electrophilic substitution in benzoic acid takes place at meta position.(ii) Carboxylic acids are higher boiling liquids than aldehydes, ketones and alcohols of comparable molecular masses.(iii) Propanal is more reactive than propanone in nucleophilic addition reactions.arrow_forward

(b) How many stereoisomers are possible for 5-hydroxyhexanal? (c) How many stereoisomers are possible for this cyclic hemiacetal? (d) Draw alternative chair conformations for each stereoisomer and label groups axial or Also predict which of the alternative chair conformations for each stereoisomer is more stable.arrow_forwardQuinapril (trade name Accupril) is used to treat high blood pressure and congestive heart failure. One step in the synthesis of quinapril involves reaction of the racemic alkyl bromide A with a single enantiomer of the amino ester B. (a) What two products are formed in this reaction? (b) Given the structure of quinapril, which one of these two products is needed tosynthesize the drug?arrow_forwardCompound A has molecular formula C7H15B.. Treatment of compound A with sodium ethoxide yields only one elimination product (compound B) and no substitution products. When compound B is treated with dilute sulfuric acid, compound C is obtained, which has molecular formula C7H160. Draw the structures of compounds A, B, and C.arrow_forward
- Draw line structures of the following compounds and the product you would obtain from the reduction of each.(a) Isopropyl methyl ketone (b) p-Hydroxybenzaldehyde(c) 2-Methylcyclopentanonearrow_forward(A) Which of the following ethers is the least soluble in water? (B) Which produces ethanol and methyl iodide after treatment with dilute HI?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
