For identification of alcohol:
1. R-OH + Na -------> R-ONa + 1/2H2 (Here identification is effervesence of H2)
 
2. R-OH + PCl5 ------> R-Cl + POCl+ HCl ---> NH3---> Nh4Cl Here identification is white fumes of NH4Cl)
3. R-OH + Cerric ammonium nitrate -----> Red Colour
 
Hope it helps
Thankyou

Hydrocarbons that contain carbon-carbon single securities are called soaked hydrocarbons. 
Lucas test: Lucas test depends on the distinction in reactivity of essential, auxiliary and tertiary alcohols with hydrogen chloride. In Lucas test, a liquor is treated with Lucas reagent (conc. HCl and ZnCl2). Turbidity is created as halides of the substituted liquor are immiscible in Lucas reagent. The time taken to accomplish turbidity is noted and taking after perceptions are made: 
•    In instance of essential liquor, turbidity is not created at room temperature. Be that as it may, on warming a sleek layer is shaped. 
•    Secondary liquor gets effortlessly oxidized to ketone yet advance oxidation is impractical. 
•    Tertiary liquor doesn't get oxidized in nearness of sodium dichromate. 
Responses of Alcohols 
Alcohols are fit for being changed over to metal salts, alkyl halides, esters, aldehydes, ketones, and carboxylic corrosive 
The response of ethanol with sodium metal (a base) produces sodium ethoxide and hydrogen gas. 
Alcohols are changed over to alkyl halides by S N1 and S N2 responses with halogen acids.
