Question

(4 + 2) cyclo addition reaction

a) Forms a 3-membered ring
b) Involves the loss of two atoms
c) Yields a racemic mixture
d) Results in a 6-membered ring

Answer 1

The (4 + 2) cyclo addition reaction forms a 6-membered ring and involves the loss of two atoms. It does not yield a racemic mixture.

Step-by-step explanation:

The (4 + 2) cyclo addition reaction forms a 6-membered ring. This reaction involves the loss of two atoms. It does not yield a racemic mixture, as the stereochemistry of the product is determined by the starting materials and reaction conditions.
