1.	Acid catalysed hydration of alkenes, except ethene, leads to the formation of
Answer» primary alcohol SECONDARY or tertiary alcohols mixture of primary and secondary alcohols mixture of secondary and tertiary alcohols Solution :Hydration of ethene gives a `1^(@)` alcohol i.e., ethanol while all other alkenes GIVE either `2^(@)` or `3^(@)` alcohols `underset("Ethene")(CH_(2)=CH_(2))underset((ii) H_(2)O, "boil")overset((i) conc. H_(2)SO_(4))rarr underset(1^(@) "alcohol")(CH_(3)CH_(2)OH)` `R-CH=CH_(2)underset((ii) H_(2)O, "boil")overset((i) conc.
