The Correct Answer and Explanation is :

Based on the chemical tests you’ve listed and their observed results, the numbers 98 and 22 likely correspond to two distinct compounds or samples that underwent testing for their reactivity and structural properties, based on the chemical tests performed.

Here’s a breakdown of the tests and possible interpretations:

1. Silver Nitrate (98):

Result: Negative

  • This test typically identifies halides (Cl⁻, Br⁻, I⁻) in organic compounds by forming precipitates with silver ions. A negative result indicates that no halide ions (chloride, bromide, or iodide) are present in sample 98.

2. Sodium Iodide in Acetone (98):

Result: Negative

  • The sodium iodide test in acetone is used to detect the presence of alkyl halides, particularly tertiary halides. A negative result suggests that sample 98 does not contain a tertiary alkyl halide.

3. Lucas Test (22):

Result: Negative

  • The Lucas test is used to distinguish between primary, secondary, and tertiary alcohols. A negative result means that sample 22 is likely a primary alcohol or does not have an alcohol group that reacts in this manner.

4. Chromic Acid (22):

Result: Positive

  • Chromic acid is used to test for the presence of primary or secondary alcohols (which get oxidized to aldehydes or ketones, respectively). A positive result indicates that sample 22 is a secondary alcohol or can be oxidized.

5. Bromine in Methanol (98):

Result: Negative

  • This test checks for the presence of unsaturation (double bonds). A negative result suggests that sample 98 does not have double bonds or is not an alkene.

6. Permanganate (98):

Result: Negative

  • Potassium permanganate is another test for unsaturation. A negative result means that sample 98 does not contain alkenes or other compounds that would be oxidized by permanganate.

7. Bromine in Methanol (22):

Result: Negative

  • Similar to the test for sample 98, the negative result for sample 22 indicates no unsaturation or alkenes.

8. Permanganate (22):

Result: Negative

  • Again, a negative result here suggests the absence of unsaturation in sample 22.

Interpretation:

  • Sample 98: The negative results in the tests for halides, tertiary alkyl groups, and unsaturation suggest that this sample could be a saturated alcohol (possibly a primary or secondary alcohol) or a compound that does not contain reactive halide or double bonds.
  • Sample 22: The positive result in the chromic acid test suggests it is likely a secondary alcohol, as secondary alcohols are oxidized by chromic acid, whereas primary alcohols are oxidized to aldehydes.

Conclusion:

  • Sample 98 likely represents a saturated alcohol or another non-reactive compound, whereas sample 22 appears to be a secondary alcohol based on the positive reaction with chromic acid. The tests suggest no halides or alkenes are present in either sample.

This analysis suggests that the unknown compounds could be a saturated alcohol (primary or secondary) for sample 98, and a secondary alcohol for sample 22. The chemical reactions conducted provide insights into the functional groups present in each sample and their reactivity.
