Interpretation:
The given cycloalkane undergoes reaction with the given Simmons-Smith reagent which is stereospecific and gives only the isomer shown. The reason has to be suggested.
Concept Introduction:
Simmons-Smith reaction: This is ultrasonication improve the rate of formation of these organic zinc compounds, as with many organometallic reactions occurring at a surface condition.
Example: The substance of a carbenoid a carbine like substance that converters
Addition Reaction:
- It is a type of reaction in which two reactants adding together to form a single product.
- It can be said as a reverse reaction of elimination reaction.
- It is a characteristic reaction of
alkane .
Hydrogenation reaction is an addition reaction in which addition of hydrogen to an unsaturated molecule occurs
Stereoisomers are isomeric molecules that have the same molecular formula and sequence of bonded atoms but differ in the three-dimensional orientations of their atoms in space.
Stereospecific reaction: reaction undergoes from a stereoisomer to a unique stereo isomeric product.

- we 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_forwardThe Williamson ether synthesis involves treatment of a haloalkane with a metal alkoxide.
