Pickling is an age-old method of preserving cucumbers by fermentation or using brine and vinegar.
Below is a simple flowchart for preparing cucumber pickles by brine fermentation method:
Selection of fresh cucumbers
$\downarrow$
Washing and sorting
$\downarrow$
Trimming ends and slicing if needed
$\downarrow$
Preparation of brine solution (5–8% salt)
$\downarrow$
Placing cucumbers in clean jars
$\downarrow$
Pouring brine to cover cucumbers completely
$\downarrow$
Covering jars with lids or cloth to allow fermentation
$\downarrow$
Fermentation at room temperature for 2–4 weeks
$\downarrow$
Checking for proper sourness and sealing jars
During fermentation, lactic acid bacteria convert sugars in cucumbers into lactic acid, which acts as a natural preservative.
This method enhances flavor, preserves texture, and extends shelf life.
Good hygiene and correct brine concentration are essential to avoid spoilage.

Choose the correct answer from the options given below:
Amines are usually formed from amides, imides, halides, nitro compounds, etc. They exhibit hydrogen bonding which influences their physical properties. In alkyl amines, a combination of electron releasing, steric and H-bonding factors influence the stability of the substituted ammonium cations in protic polar solvents and thus affect the basic nature of amines. Alkyl amines are found to be stronger bases than ammonia. Amines being basic in nature, react with acids to form salts. Aryldiazonium salts, undergo replacement of the diazonium group with a variety of nucleophiles to produce aryl halides, cyanides, phenols and arenes.
