Place the following alcohols in decreasing order of rate of dehydration with `H_(2)SO_(4)`. `CH_(3)CH_(2)CHunderset((A))((OH))CH_(2)CH_(2)CH_(3)` `(CH_(3))_(2)Cunderset((B))((OH))CH_(2)CH_(2)CH_(3)` `(CH_(3))_(2)Cunderset((C))((OH))CH(CH_(3))_(2)` `CH_(3)CH_(2)CHunderset((D))((OH))CH(CH_(3))_(2)` `CH_(3)CH_(2)CH_(2)underset((E))(CH_(2))CH_(2)CH_(2)OH`A. `III gt II gt IV gt V I`B. `III gt II gt IV gt I gt V`C. `III gt II gt I gt IV gt V`D. `III gt II gt I gt V gt IV` |

Answer» Correct Answer - B The alcohols (II) and (III) both are `3^(@)`, but alcohol (III) gives a more substituted alkene, Alcohol (IV) and (I) both are `2^(@)`, but alcohol (IV) can give a more substituted alkene and alcohol (V) is `1^(@)`.Rate of dehydration of alcohols with conc. `H_(2)SO_(4)` follows the order `3^(@) gt 2^(@) gt 1^(@)` |
