trans-2-pentene is $$C_5 H_{10}$$, and has a double bond between the 2nd and 3rd carbons. The methyl and ethyl groups are trans to one another across the double bond. The double bond is also a site of unsaturation.

From http://www.neath-porttalbot.gov.uk/html/environment/pollution/on-line/species/t2pe.html [Broken],

"Trans-2-pentene is a polymerization inhibitor, a solvent and intermediate for the manufacture of petroleum resins and amyl alcohols.

Its toxicological properties have not been thoroughly investigated but vapors are irritating to the respiratory tract. Coughing, laryngitis and shortness of breath may occur at high concentrations. Inhalation may also cause dizziness."

Hope this helps

Hmm...any particular feature or problem? More specifically, how does trans-2-pentene trouble you?
