Question

Observed the following reaction sequence and identify the correct option(s)?

• A. (F) reacts with $KMn{O}_4/H^{+}$ gives phthalic acid which upon heating gives phthalic anhydride
• B. (E) upon monochlorination $\left(C{l}_2/h\nu \right)$ gives total four products
• C. (F) upon complete catalytic hydrogenation gives saturated compound which show geometrical isomerism
• D. Compound (A) gives a positive test with $NaHC{O}_3$

Answer 1

Answer: (A), (B), (C), (D)

The correct options are
A (F) reacts with $KMn{O}_4/H^{+}$ gives phthalic acid which upon heating gives phthalic anhydride
B (E) upon monochlorination $\left(C{l}_2/h\nu \right)$ gives total four products
C (F) upon complete catalytic hydrogenation gives saturated compound which show geometrical isomerism
D Compound (A) gives a positive test with $NaHC{O}_3$





Compound (A) is carboxylic acid and hence react with $NaHC{O}_3$ to liberat $C{O}_2$ along with formation of corresponding salt.
