- Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died. Q.) Methyl isocyanate reacts with strong acids, such as sulfuric acid, to form a cation. Will this molecule undergo protonation more readily on its oxygen or nitrogen atom? In considering contributing structures to each hybrid, do not consider structures in which more than one atom has an incomplete octetarrow_forwardDraw the formulas of the reactants and products of the reaction: 2-ethylbutanoyl bromide with excess ethylmagnesium bromide and heating the product with concentrated H2SO4.arrow_forward4) Provide the starting materials for the following reactions. a) b) c) HBr 0 °C H₂O, H₂SO4 NaOH (2 equivalents) H₂O, 55 °C OH Brarrow_forward
- CH3 CH3 H cyclopentamine The synthesis of cyclopentamine, an amphetamine-like central nervous system stimulant, from materials of five carbons or fewer involves several steps, one of which is shown below. Draw the structure(s) of the major organic product(s) of the following reaction: Mg, dry ether Br productarrow_forwardBent (D) Trigonal pyramidal 5. A student wishes to prepare ethyl acetate from the reaction of ethanol and acetic acid. To be successful, this reaction requires (A) an acidic catalyst. (C) an oxidizing agent. (B) a basic catalyst. (D) a reducing agent. 6. Which alkyl halide reacts most rapidly with aqueous sodium hydroxide solution? (A) CH₂Cl (B) CH₂I (C) (CH3)3CCH₂Cl (D) (CH3)3CCH₂I 57.

- Synthesize each compound.You may use benzene, acetylene (HC≡CH), ethanol, ethylene oxide, and any inorganic reagents.arrow_forwardWrite the reagent or draw structures of the starting material or organic product(s) in the following reactions. If more than one product is formed, identify the major product where possible. (a) (b) HO OH OH H2SO4 ? Cl₂ ? FeCl3arrow_forwardCompounds A and B are isomers of the molecular formula CyH19Br. Both yield the same alkene Cin an elimination reaction. Hydrogenation of C yields the product 2,3,3,4 tetramethyl pentane. What are the structures of A, B, and C?arrow_forward
- Citronellol ((3R)-3,7-dimethyloct-6-en-1-ol, C10H20O) is an organic fragrance found in the oil extracted from lemon grass. a) Name the two functional groups present in the molecule. b) When a few drops of bromine dissolved in hexane is added to a sample of citronellol the brown colour of the bromine rapidly disappears. i. What type of chemical reaction has occurred? ii. Draw the structure of the product formed. iii. Name the product. c) The product formed when citronellol is heated with a mixture of potassium dichromate and sulfuric acid gives a yellow/orange precipitate when shaken with Brady’s reagent (2,4-dinitrophenylhydrazine). It also shows a positive result with Fehling’s solution. i. What type of chemical reaction has occurred ? ii. What type of functional group is present in the product? d) Explain the type of stereoisomerism which may occur in citronellol.arrow_forwardFormaldehyde, H2C=O, is known to all biologists because of its usefulness as a tissue preservative. When pure, formaldehyde trimerizes to give trioxane, C3H6O3, which, surprisingly enough, has no carbonyl groups. Only one monobromo derivative (C3H5BrO3) of trioxane is possible. Propose a structure for trioxane.arrow_forwardSeveral diamines are building blocks for the synthesis of pharmaceuticals and agro-chemicals. Show how both 1,3-propanediamine and 1,4-butanediamine can be prepared from acrylonitrile.arrow_forward
