Document Summary
Organic molecules: carbon-containing molecules: originally discovered in living organisms and could not be synthesized. Vitalism: belief that organic molecules were imparted with a vital life force. )n (cid:883)8(cid:884)8 friedrich wohler synthesized urea (cid:498)without the use of kidneys, either man or dog(cid:499) Carbon is the chemical basis of all life. Carbon bonds may occur in linear, ring-like, or highly branched configurations: offers diversity in terms of shape/structure of molecules, these molecular shapes can produce molecules with a variety of functions. Can form both polar and nonpolar bonds, and single and double bonds. Carbon bonds are stable at the different temperatures associated with life. Carbon atoms are small, resulting in short carbon-carbon bonds: stronger and more stable due to close proximity. Makes life possible even in extreme environments. Groups of atoms with special chemical features that contribute to the. Each type of functional group exhibits the same properties in all molecules in.
