Question

Post-Lab Questions I. Write the structural formulas for the two (2) chloro-isomers that can be formed from 2-methylpropane Gisobutene). How many sets of equivalent hydrogen are there in the 2. Given the molecular formula C,H,Br, draw all the structural isomers that are possible. 3. Using the Newman projection, draw a staggered conformer and an eclipsed conformer for 1-chloropropane, CI-CH2-CH2-CH, along the bond indicated by (). Why can these conformers be interconverted? stagered 4. What structural feature prevents the conversion of cis-2-butene into trans-2-butene by a simple rotation? 5. Below are structures for three carbon compounds. What is the common characteristic for each of the carbons identified by ()? CH3-CH2-CH3 CH3-CH=CH2 252

Explanation / Answer

1.

2-Methylpropane

CH3-CH(CH3)-CH3

Chloro isomers:

1. CH3-CH(CH3)-CH2Cl 1-Chloro-2-methylpropane

2. CH3-C(Cl)(CH3)-CH3 2-Chloro-2-methylpropane

****

There are to equivalent hydrogens in 2-Methylpropane.

One type is the 9 terminal hydrogens and second type is the hydrogen at second carbon.
