Options

A. `CH_(3)CH=CH_(2)`
B. `CH_(3)C-=CH`
C. `CH_(3)CH_(2)CH_(3)`
D. `CH_(2)=C=CH_(2)`

Answer

A

Explanation

`CH_(3)CH = CH_(2) overset(CI_(2))underset(480-500^(@)C)rarr underset("alkyl chloride")(CICH_(2)CH = CH_(2))`

`underset("glycerol-beta-monochlorohydrine")(HOCH_(2)CHCICH_(2)OH)overset(NaOH)rarr underset("glycerol")(HOCH_(2)CHOCH_(2)OH)`
Glycerol `("propane"-12,3-"triol"),b.p. 290^(@)C`, is the only important trihydric alcohol. It occurs in almost all animal and vegetable alcohol. It occurs in almost all animal and vegetable oils and fats as the glyceryl esters of mainly plamitic, stearic and oleic acids. Glycerol is obtanied in large quantities as a by-product in the manugacture of soap:
