Elucidate the structure, hybridization, stability
order and factors affecting the stability of an
organic intermediate which is formed by the
homolytic bond breaking.
An organic compound A of unknown structure was found to have a molecular formula C8H16. When A was poured in water and heated, compound B having a molecular formula C8H18O was formed. B upon heating with sulfuric acid was converted to C as the major product which is identical to A. Ozonolysis of C gave one molecule each of two different products D and E, both having a molecular formula C4H8O. Write the reactions involved and determine the structure of A,B,C,D and E.
Grignard reagent is a versatile tool in synthetic organic chemistry. Using bromocyclopentane as a starting material, show how a Grignard reagent, X, is synthesized.
Reaction of X with water produces compound Y while treatment in carbon dioxide followed by hydrolysis forms compound Z. 3-methyl-2butanone reacts with X and hydrolyses to yield compound AA. Draw the structural formulae of compounds Y, Z and AA and write the chemical equations respectively.

- A problem often encountered in the oxidation of primary alcohols to acids is that esters are sometimes produced as by-products. For example, oxidation of ethanol yields acetic acid and ethyl acetate: Propose a mechanism to account for the formation of ethyl acetate. Take into account the reversible reaction between aldehydes and alcohols:arrow_forwardWhen bromomethane undergoes solvolysis in a solvent mixture composed of 90% water/10% acetone, the reaction rate is faster than when the same compound is solvolyzed in 80% water/20% acetone. Explain.arrow_forwardWhen butane reacts with Br₂ in the presence of Cl₂, both brominated and chlorinated products are obtained. Under such conditions, the usual selectivity of bromination is not observed. In other words, the ratio of 2-bromobutane to 1-bromobutane is very similar to the ratio of 2-chlorobutane to 1-chlorobutane. Can you offer and explanation as to why we do not observe the normal selectivity expected for bromination? Chlorine radicals perform the first propagation step (hydrogen abstraction) comparison to bromine radicals. Under these conditions in radicals form easily in the presence of chlorine radicals. Subsequently, the resulting radicals can react with bromine in a second propagation step to yield monobrominated products.arrow_forward

- Explain the following observations :(i) The boiling point of ethanol is higher than that of methoxymethane.(ii) Phenol is more acidic than ethanol.(iii) o- and p-nitrophenols are more acidic than phenol.arrow_forwardwe know that ethers, such as diethyl ether and tetrahydrofuran, are quite resistant to the action of dilute acids and require hot concentrated HI or HBr for cleavage. However, acetals in which two ether groups are linked to the same carbon undergo hydrolysis readily, even in dilute aqueous acid. How do you account for this marked difference in chemical reactivity toward dilute aqueous acid between ethers and acetals?arrow_forwardA hydrocarbon (X), with the molecular formula: C8H14 is reduced in presence of sodium and liquid ammonia to give the only product (Y) with the molecular formula: C8H16. Compounds X and Y both resulting 2,5-dimethylhexane when treated with hydrogen and platinum catalyst (H2/Pt). As a result of the oxidative cleavage of compound Y (by using KMnO4 / H2SO4), a single carboxylic acid derivative with C4H8O2 molecular formula is formed. Again, as a result of the reaction of Y with perbenzoic acid, the chiral compound C8H14O is observed, but the reaction of compound Y with bromine gives the achiral C8H14Br2 as the product.arrow_forward
