Can alcohols be dehydrated to form alkenes

WebThe result is that in the temperature range of ca. 200–350 °C (and at the relevant associated confining pressures), alcohols can undergo quite rapid dehydration to form alkenes, even though they are in the presence of … Web• The dehydration of alcohols with aqueous acid is an E1 process and occurs through the three-step mechanism. Only tertiary alcohols are readily dehydrated with acid. Secondary alcohols can be made to react but the conditions are severe. Primary alcohols are even less reactive and very harsh conditions are necessary to cause dehydration.
