WebIn these cyclic forms, the ring usually has five or six atoms. These forms are called furanoses and pyranoses, respectively—by analogy with furan and pyran, the simplest compounds with the same carbon-oxygen ring (although they lack the double bonds of these two molecules).
WebYou are forming a carbon ring, and a 6-membered ring has the most stable bond angle, which is why you have C1-C2-C3-C4-C5-O as your ring structure. Btw, 5 membered rings also occur naturally (see: ribose) but they are simply not as stable. And if 6 is possible, why settle for 5? :-) 3 comments ( 7 votes) Show more...
