Cyclopropane symmetry elements

Cyclopropane is the cycloalkane with the molecular formula (CH2)3, consisting of three methylene groups (CH2) linked to each other to form a ring. The small size of the ring creates substantial ring strain in the structure. Cyclopropane itself is mainly of theoretical interest but many of its derivatives are of commercial or biological significance. WebList all the symmetry elements of the following molecules, assign each to a point group, and state whether they form enantiomers: (a) lactic acid, (b) trans- [Co (ethylenediamine)_2 Cl_2]^+, (c) cis- [Co (ethylenediamine)_2 Cl_2]^+, (d) cyclopropane, (e) trans-1, 2-dichlorocyclopropane, (f) 1-chloro-3-fluoroallene.

WebCyclopropane is necessarily planar (flat), with the carbon atoms at the corners of an equilateral triangle. The 60º bond angles are much smaller than the optimum 109.5º angles of a normal tetrahedral carbon atom, and the resulting angle strain dramatically influences the chemical behavior of this cycloalkane.

WebThe molecule has D 3h molecular symmetry. The C-C distances are 151 pm versus 153-155 pm. [15] [16] Despite their shortness, the C-C bonds in cyclopropane are weakened by 34 kcal/mol vs ordinary C-C bonds. In addition to ring strain, the molecule also has torsional strain due to the eclipsed conformation of its hydrogen atoms.
