1^{\circ }>2^{\circ }>3^{\circ }

- wherein

ROH+Na\rightarrow 2RONa+H_{2}

 

 

Alcohols reaction with phosphorus trihalides -

Form alkyl halides 

- wherein

ROH+PX_{3}\rightarrow RX+H_{3}PO_{3}

X = Cl, Br, I

 

 C_{2}H_{5}OH\xrightarrow[]{Na} C_{2}H_{5}O^{-}Na^{+}

        A                            B

C_{2}H_{5}OH\xrightarrow[]{PCl_{5}} C_{2}H_{5}Cl

        A                               C
