- Compound A and compound B are different alcohols with the same molecular formula of C4H10O. When reacted with chromic acid (H2CrO4), compound A and compound B produce compound C and compound D, respectively. Compound C has a molecular formula of C4H8O2. Compound E is obtained when compound A reacts with pyridinium chlorochromate (PCC) in a solvent such as dichloromethane (CH2Cl2). Draw the structure of compound A, B, C, D and E.arrow_forward#1077 of Paperchasel Compound A is treated with H₂SO4 to produce compound B which decolourises bromine in CCl4 Compound B is treated with cold, dilute KMnO4 to produce compound C. If compound A has the molecular formula C6H₁2O then: Select one: O a. B could be 1-hexene and C could be 1,2-hexanediol b. A could be cyclohexanol and B could be cyclohexane O c. A could be cyclohexanone and B could be cyclohexene O d. A could be cyclohexanol and C could be 1,2-cyclohexanediol e.

Compound A, C 10H 18O, undergoes reaction with dilute H 2SO 4 at 50 °C to yield a mixture of two alkenes, C 10H 16. The major alkene B, gives only cyclopentanone after ozone treatment followed by reduction with zinc in acetic acid. Which of the following reactions are correct.arrow_forward
- Compound W has molecular formula C₁4H18 and reacts with H₂ to form X. Oxidative cleavage of W with O3 followed by CH3 SCH3 affords Y. What is the structure of W?arrow_forwardIn an advanced synthetic chemistry experiment, a researcher prepares a compound, ZY-7, by reacting a ketone (C5H100) with hydroxylamine (NH2OH), followed by heating in the presence of an acid catalyst. The resulting compound, ZY-7, is then treated with a solution of sodium nitrite (NaNO2) and hydrochloric acid (HCI) at low temperature. Identify the class of compound that ZY-7 most likely belongs to after this series of reactions." A) Amide B) Oxime C) Nitro compound D) Diazonium salt E) Ester Don't use chatgpt please provide valuable answerarrow_forwardCompound H with molecular formula C6H12O showed no reaction in chromic acid test. Compound H undergo dehydration reaction to produce compound I. Compound J is produced when compound I react with HBr. Reaction of compound J with methanol produced compound K and I. Draw the structure of H, I, J, and K.arrow_forward
