Answer 13.
d) II is the correct answer
Diels elder reaction is the chemical reaction between a conjugated diene and a substituted alkene, commonly termed as dienophile, to form a substituted cyclohexene derivative.
Answer 14.
Degree of unsaturation of C9H9NO4 is 6.
DU = C + 1 + N/2 - H/2
= 9 + 1 + 1/2 - 9/2
= 10 - 4
= 6
