Which of the statement given below concerning 3-methyl-2-butanol is/ar...

Explanation:

Treatment with cold, concentrated H2SO4
- Treatment with cold, concentrated H2SO4 converts 3-methyl-2-butanol into achiral 2-methyl-2-butanol.
- This reaction involves the dehydration of the alcohol to form an alkene, resulting in the loss of chirality.

Treatment with NaOH solution
- Treatment with NaOH solution does not convert 3-methyl-2-butanol into 2-methyl-2-butanol. This statement is incorrect.

Treatment of its pure enantiomer with PCl5
- Treatment of the pure enantiomer of 3-methyl-2-butanol with PCl5 gives mainly a pure enantiomer of chloroalkane.
- This reaction involves the replacement of the hydroxyl group with a chlorine atom, maintaining the chirality of the molecule.

Change in the color of acidic K2Cr2O7 solution
- 3-methyl-2-butanol changes the orange color of acidic K2Cr2O7 solution to blue-green.
- This indicates the oxidation of the alcohol to a ketone, causing the color change in the chromium solution.
