Concept explainers
Interpretation:
It should explained that why was a deuterated compound used in the given reaction.
Concept introduction:
Pericyclic reactions are “ any concerted reaction in which bonds are formed or brocken in a cyclic transition state”. There is a single transition state from start to finish, in contrast to a stepwise reaction.
There are mainly three types of pericyclic reactions,
- 1) Electrocyclic reactions
- 2) Cycloaddition reactions
- 3) Sigmatropic reactions
In a sigmatropic reaction “ one new sigma-bond is formed as another breaks.”
Sigmatropic rearrangement reactions are named with digits. For example a [1, 3] sigmatropic rearrangement describe a reaction in which the residue migrates from position 1 to position 3.

Only use ones available in the answer bank please.arrow_forwardWhat is this reaction’s productarrow_forwardCan the alkyl halide in the drawing area be made in one step from an alcohol, without losing starting material to unwanted extra products? If so, add the alcohol starting material to the left-hand side of the reaction, and the necessary reagents above or below the arrow. If the alkyl halide can't be made in one step, or can't be made in good yield because of competing reactions or unwanted byproducts, check the box under the drawing area.
