Propose structures for compounds E-H. Compound E has the molecular formula C5H8 and is optically active. On catalytic hydrogenation E yields F. Compound F has the molecular formula C5H10, is optically inactive, and cannot be resolved into separate enantiomers. Compound G has the molecular formula C6H10 and is optically active. Compound G contains no triple bonds. On catalytic hydrogenation G yields H. Compound H has the molecular formula C6H14, is optically inactive, and cannot be resolved into separate enantiomers.
