• All the above

Complete the following reaction
R-OH + PCl5  $\rightarrow$  RCl + X + HCl
X is

• PCl3

• PCl5

• POCl3

• POBr3

complete the following reaction

The halogenation of alkanes gives alkyl halide which are

• Positional isomers

• Chain isomers

• Functional isomers

• Metamers

In SN¹ the order of reactivity of halide is:

• 3⁰ > 2⁰ > 1⁰ > methyl

• Methyl > 1⁰>2⁰ > 3⁰

• 3⁰ > 2⁰ > methyl > 1⁰

• 2⁰ > 1⁰ > methyl > 3⁰
