Treatment of A (C5H12O) with concentrated sulphuric acid results in the formation of three alkenes in differing yields. Also, A forms a yellow precipitate on treatment with NaOH/I2. A turns colour of acidified dichromate solution to blue green, forming a new organic compound B which also forms yellow precipitate on treatment with NaOH/I2. The most likely name of A is 
  • a)
    3-methyl-2-butanol
  • b)
    3-methyl butanol
  • c)
    2-pentanol
  • d)
    Either (b) or (c)
Correct answer is option 'A,C'. Can you explain this answer?

Identification of Compound A:
- The most likely name of A is 3-methyl-2-butanol as it has the molecular formula C5H12O.
- Compound A forms a yellow precipitate on treatment with NaOH/I2, indicating the presence of a secondary alcohol group.

Chemical Reactions of Compound A:
- Treatment of A with concentrated sulphuric acid results in the formation of three alkenes in differing yields. This suggests that A is a tertiary alcohol.
- A turns the color of acidified dichromate solution to blue-green, indicating the presence of a tertiary alcohol group.

Identification of Compound B:
- Compound B is formed by the oxidation of A with acidified dichromate solution, suggesting that B is an aldehyde or ketone.
- Compound B also forms a yellow precipitate on treatment with NaOH/I2, indicating the presence of an aldehyde or ketone group.

Therefore, the most likely name of compound A is 3-methyl-2-butanol, and compound B is an aldehyde or ketone derived from the oxidation of A.
