Which of the following is/are correct about the Diels-Alder reaction? (a) It is a concerted $[4+2]$ cycloaddition reaction. (b) It is stereospecific reaction (c) The products are either cyclohexane or 1,4 cyclohexadiene derivatives. (d) It requires an s-cis diene and dienophile.
3. What does the term 'concerted reaction' mean? 4. Why is maleic anhydride a better dienophile than ethylene (CH2=CH2)?
