Question

4-Mctul-2-exene Geometry of Alkenes (Section 12.2) 12.13 What type of hybridized orbitals are present on carbon atoms bonded by a double bond? How many of these hybrid orbitals are on each carbon atom 12.15 Describe the geometry of the carbon-carbon double bond and the two atoms attached to each of the double-bonded carbons. 12.17 Draw structural formulas and give IUPAC names for all the isomeric pentenes (C5H10) that are: a) Alkenes that do not show geometric isomerism (4 possible compounds). b) Alkenes that do showgeometric isomerism (one cis-& one trans- compound).
