Question

what statement about Diels-Alder reaction is wrong?

a. a diels alder reaction has translation state

b. a diels alder reaction has an intermidiate state

c. a diesk alder reaction is concerted

d all of above

What statement about diels alder reaction is true

a. a typical diels-alder reaction forms potentially two new sterocenters.

b. a typical diels-alder reaction is thermodynamically controlled.

c.a typical diels-alder reaction forms potentially 4 new sterocenters.

d. a typical diels-alder reaction forms potentially 6 new sterocenters.

Answer is option B

Deals alder reaction is a cyclo addition reaction

in this diene react with dienophile and form the product

this is an example for peri cyclic cyco addition reaction

in peri cyclic reactipons there is no ntermediates there is only transition state

here bond breaking and bond forming takes place simultanuously

so option B is wrong

Answer is option B

the number od stereo centers formed in this reaction depends on kind of starting material you have taken

it can be either two or four

but dieals alder reaction is always thermo dynamically controlled reaction

thermodynamically mpre stable product will form always major
