Question

Which one among the following alcohols will give iodoform on treatment with iodine and sodium hydroxide? (A) C6H5- underset overset|OHCH-C6H5 (B) H3C-OH  (C) C6H5- underset overset|OHCH-CH3 (D) H3C-CH2 underset overset|OHCH-C6H5

The compounds containing CH3- overset underset|||OHC and CH3 - overset underset|OHC -H groups on heating with (aq) NaOH +I2 gives iodoform test (yellow ppt of iodoform). Therefore, the compound, C 6 H 5- underset overset|OHC H - CH 3 gives iodoform test.

Q. Which one among the following alcohols will give iodoform on treatment with iodine and sodium hydroxide?

$C_{6} H_{5} - O H ∣ C H - C_{6} H_{5}$

$H_{3} C - O H$

$C_{6} H_{5} - O H ∣ C H - C H_{3}$

$H_{3} C - C H_{2} O H ∣ C H - C_{6} H_{5}$

The compounds containing $C H_{3} - C ∣∣∣ O H$ and
$C H_{3} - C ∣ O H - H$ groups on heating with (aq) $N a O H + I_{2}$
gives iodoform test (yellow ppt of iodoform).
Therefore, the compound, $C_{6} H_{5} - O H ∣ C H - C H_{3}$ gives iodoform test.

Q. Which one among the following alcohols will give iodoform on treatment with iodine and sodium hydroxide?

C6​H5​−OH∣C​H−C6​H5​

H3​C−OH

C6​H5​−OH∣C​H−CH3​

H3​C−CH2​OH∣C​H−C6​H5​

The compounds containing CH3​−C∣∣∣OH​ and CH3​−C∣OH​−H groups on heating with (aq) NaOH+I2​ gives iodoform test (yellow ppt of iodoform). Therefore, the compound, C6​H5​−OH∣C​H−CH3​ gives iodoform test.

$C_{6} H_{5} - O H ∣ C H - C_{6} H_{5}$

$H_{3} C - O H$

$C_{6} H_{5} - O H ∣ C H - C H_{3}$

$H_{3} C - C H_{2} O H ∣ C H - C_{6} H_{5}$

The compounds containing $C H_{3} - C ∣∣∣ O H$ and
$C H_{3} - C ∣ O H - H$ groups on heating with (aq) $N a O H + I_{2}$
gives iodoform test (yellow ppt of iodoform).
Therefore, the compound, $C_{6} H_{5} - O H ∣ C H - C H_{3}$ gives iodoform test.
