Answer» Correct Answer - C The compounds cotaining `CH_(3)-underset(OH)underset("| ")"CH"-` group are distinguished from other alcohols through iodoform test (reaction of alcohol with `I_(2)` and aq. NaOH.) `underset("Propanol")(CH_(3)-CH_(2)-CH_(2)OH)+I_(2)+NaOH overset(Delta)rarr "No reaction"` `underset("2-Propanol")(CH_(3)-underset(OH)underset("| ")"CH"-CH_(3))+4I_(2)+6NaOH overset(Delta)rarr underset("lodoform")(CHI_(3)darr)+underset("Sodium acetate")(CH_(3)COoverset(-)(O)overset(+)Na+5overset(+)(Na)overset(-)I+5H_(2)O` |
