1.	Dehydration of which of the following alcohols produce alkenes exhibiting cis-trans-isomerism ?
Answer» ISOPROPYL alcohol Tertiary butyl alcohol Secondary butyl alcohol 3-Pentanol Solution :Both `2^@` butyl alcohol and 3-pentanol on DEHYDRATION GIVE alkenes which show cis-trans isomerism. `UNDERSET(2^@ "Butyl alcohol")(CH_3-CHOH-CH_2CH_3)underset((-H_2O))overset"Dehydration"to underset"2-Butene"(CH_3-CH=CH-CH_3)` `underset"3-Pentanol"(CH_3CH_2-CHOH-CH_2CH_3)underset((-H_2O))overset"Dehydration"to underset"2-Pentene"(CH_3CH_2-CH=CHCH_3)`
