Question

If i could get some help on either of these 2 worksheets i would greatly appreciate it! Thanks so mich!

do some molecules with the same formula (or even connectivity!) have different properties? ACQUIRE (USING MODELS!) 1. Fill in the following tables and BUILD each structure as you go. Have your instructor check your answers after each table or as directed Name and Condensed structure Skeletal structure Molecular formula Name: C8H18 2,3-dimethylhexane Molecular formula: C&HI8 Constitutional (structural) isomer of A CSHIB Name: В Molecular formula: Name: 2-methyl 3- ethy LRentane с CBH18 CH3 CH2 CH- -CH2-CH Molecular formula: CH3-CH- CH3 CHS) Constitutional (structural) isomer of C Name: Molecular formula:

as to is a structural roomer of E&F because in strutural loomers connectinty from atom to atom changes and in stereo isomers, connectivity from atom to atom does not change only orientation of molecule in 3-D changes. by stereoisomer of G is not possible because neether there is a sterio centre in the molecule nor there can be cid-trans(qumetrical romerions for geometrical raomenism, carben containing double Band must contain different groups, In a b xa, they H2C1 This carbon contains two- CH₂ quoup. ex. Hal are aterioisomers. C containing four different groups, moreover they are non superimposable muror images q each other. They are enantiomers, C contains four different gecoups in H&I four different groups are H, af, ace & -Br. This is called Cheral centre
