Web23 jul. 2014 · 1. Nucleophilic addition of hydrogen cyanide to ethanal 2 Hydrolysis of the nitrile group H+ / H2O HCN During the first stage, the nucleophilic CN- ion can attack from below, or above, the aldehyde. A mixture of the two enantiomers is formed. Acid hydrolysis of the mixture provides a mixture of the two lactic acid forms. WebTranscribed image text: (a) But-2-ene, CH,CH=CHCH), exists as geometric isomers. (1) Draw the geometric isomers of but-2-ene. (2) (ii) Explain how geometrie isomerism arises. (1) (6) 0 Draw the structural formula of a compound which is an isomer of but-2-ene but which does not show geometric isomerism. Web"2-butene" indicates a chain of four carbons, with a double bond between carbons 2 and 3. Double-bonded carbons are sp2-hybridized, and have trigonal planarshapes, with the bonded atoms at angles of 120° to each other. Free rotation is not possible around carbon-carbon double bonds in alkenes, making the carbon chains less flexible graphite coated canvas roll
