Question

An effect named for this word increases the lability of certain ligands in square planar complexes, such as one that contains platinum. (20[1])Upon absorbing a photon, the pigment retinal enters a state of being entirely described by this word. When the two groups with the highest priority according to CIP ("C-I-P") rules are described by this word, (0[1])a (*) double bond has an E configuration. (10[1])Substituents added by an "anti" addition are described by this word. Partial hydrogenation produces a type of unsaturated fat known by this word that is banned in many countries (10[1])due to its health (10[2])effects. For 10 points, give this word that describes a conformation in which groups are on opposite sides of a bond, contrasted with cis. ■END■ (10[2])

ANSWER: trans [accept trans configuration or trans isomer; accept trans effect; accept all-trans retinal; accept trans fat]
