Two reactions I and II are given below:

Correct statement regarding the reactions is

Which of the following sets of reagents are required for the conversion of ethyl bromide to propanoic acid?

Which is the correct order of acid strength from the following?

Which of the following compounds contains the -COOH (carboxylic) group?

Tomato is a natural source of which acid?

Arrange the following compounds A, B, C, and D in decreasing order of acidic strength:


Choose the correct answer from the options given below:

Which of the following isomer of 1, 2-cyclohexanedicarboxylic acid forms an hydride on heating?

Which one of the given compounds is a stronger acid and why?
CH$_2$FCH$_2$COOH or CH$_3$CHFCH$_2$COOH

Assertion (A): Benzoic acid does not undergo Friedel – Crafts reaction.
Reason (R): Carboxyl group is deactivating and the catalyst aluminium chloride gets bonded to the carboxyl group.

Write the structures of A and B in the following reaction: \[ \text{C}_6\text{H}_5\text{COOH} \xrightarrow{\text{NH}_3, \Delta} A \xrightarrow{\text{Br}_2/\text{NaOH}} B \]

Complete the following reaction: \[ \text{C}_6\text{H}_5\text{N}_2^+Cl^- \xrightarrow{\text{(i) HBF}_4} \xrightarrow{\text{(ii) NaNO}_2/\text{Cu}, \Delta} \quad ? \]

Assertion (A): The pK$_a$ of O$_2$N–CH$_2$–COOH is lower than that of CH$_3$–COOH. Reason (R): The –NO$_2$ group shows an electron-withdrawing effect, which increases the acidic character of O$_2$N–CH$_2$–COOH.
