How is ethyl iodide prepared from ethanol?
When ethanol is treated with phosphorus triiodide then, it forms ethyl iodide.
3C2H5OH +PI3 --> 3C2H5I + H3PO3
What happens when CH3-CH2CH2-Cl is boiled with alcoholic KOH?
When chloro propane is boiled with alcoholic KOH then, it forms propene
CH3-CH2CH2-Cl + alc. KOH --> CH3-CH2=CH2
Give one chemical test to distinguish between C2H5Br and C6H5Br.
Hydrolysis of C2H5Br with refluxing aqueous KOH followed by acidification with dil HNO3 and subsequent treatment with AgNO3 gives light yellow ppt. of AgBr whereas C6H5Br does not gives this test.
