Question

In which of the following conversions, phosphorus pentachloride is used as the reagent? (A) H 2 C = CH 2 arrow CH 3 CH 2 Cl (B) CH 3 CH 2 OH arrow CH 3 CH 2 Cl (C) H 3 C - O - CH 3 arrow CH 3 Cl (D) HC ≡ CH arrow CH 2= CHC 1

CH 3- O - CH 3+ PCl 5 arrow 2 CH 3 Cl + POCl 3 CH 3 CH 2 OH + PCl 5 arrow CH 3 CH 2 Cl + HCl + POCl 3 So, both reaction carried out by PCl 5

Q. In which of the following conversions, phosphorus pentachloride is used as the reagent?

$H_{2} C = C H_{2} \to C H_{3} C H_{2} Cl$

$C H_{3} C H_{2} O H \to C H_{3} C H_{2} Cl$

$H_{3} C - O - C H_{3} \to C H_{3} Cl$

$H C \equiv C H \to C H_{2} = C H C 1$

$C H_{3} - O - C H_{3} + PC l_{5} \to 2 C H_{3} Cl + POC l_{3}$
$C H_{3} C H_{2} O H + PC l_{5} \to C H_{3} C H_{2} Cl + H Cl + POC l_{3}$
So, both reaction carried out by $PC l_{5}$

Q. In which of the following conversions, phosphorus pentachloride is used as the reagent?

H2​C=CH2​→CH3​CH2​Cl

CH3​CH2​OH→CH3​CH2​Cl

H3​C−O−CH3​→CH3​Cl

HC≡CH→CH2​=CHC1

CH3​−O−CH3​+PCl5​→2CH3​Cl+POCl3​ CH3​CH2​OH+PCl5​→CH3​CH2​Cl+HCl+POCl3​ So, both reaction carried out by PCl5​

$H_{2} C = C H_{2} \to C H_{3} C H_{2} Cl$

$C H_{3} C H_{2} O H \to C H_{3} C H_{2} Cl$

$H_{3} C - O - C H_{3} \to C H_{3} Cl$

$H C \equiv C H \to C H_{2} = C H C 1$

$C H_{3} - O - C H_{3} + PC l_{5} \to 2 C H_{3} Cl + POC l_{3}$
$C H_{3} C H_{2} O H + PC l_{5} \to C H_{3} C H_{2} Cl + H Cl + POC l_{3}$
So, both reaction carried out by $PC l_{5}$
