Question

a. Identify the mode of ring closure for the following electrocyclic reactions.
b. Are the indicated hydrogens cis or trans?

Expert Solution

Step 1

The given electrolytic reaction is,

Step 2

(a)

For electrocyclic reaction, Woodward-Hoffmann rules could be given as,

Number of conjugated $π$ bonds	Reaction conditions	Permitted mode of ring closure
Even number	Thermal condition	Conrotatory
	Photochemical	Disrotatory
Odd number	Photochemical	Conrotatory
	Thermal	Disrotatory

The number of $π$ bonds in the given compound is two and the reaction occurs in thermal condition. Based on Woodward-Hoffmann rule, conrotatory is the mode of ring closure.
