How will you distinguish between 1-phenylethanol and 2-pheylethanol ?

Explanation

By iodoform test. 1-Phenylethanol contains the grouping -CHOH-`CH_(3)` linked to carbon and hence gives iodoform test while 2-phenylethanol does not contains the grouping -`CHOH-CH_(3)` and hence does not give iodoform test.
`underset("1-Phenylethanol")(C_(6)H_(5)-CHOH-CH_(3)) overset(I_(2)//NaOH) to underset("Iodoform")(CHI_(3)): underset("2-Phenylethanol")(C_(6)H_(5)CH_(2)CH_(2)OH) overset(I_(1)//NaOH)to ` No reaction.
