Question : Why is the general formula for a cyclic alkane CnH2n instead of CnH2n+2 as found in a noncyclic alkane?
Answer : Because two of the carbon molecules join to each other in a circle, rather than holding onto a hydrogen atom.
Picture 6 people standing in a line, arms outspread, holding each others hands. The two on the ends are holding an apple in their single open hands. They have to put those two apples down in order to make a circle and hold each others hands.
Those two apples (representing the hydrogren atoms) are the +2 that you lose when a straight-chain alkane becomes a cyclic alkane.
Question : illistrate ur anwser with an example of each type of pathway?
Answer : Bekah, is this a homework problem? You little minx.
OK, anyway. Linear means in a line. There's starting and ending points. Like the clotting cascade. It is irreversible.
A cyclical reaction is a continuous one. Like the Krebbs energy cycle.
Question : I have a heterocyclic molecule that contain an amine within the ring and one on a side chain. I'm looking for an adjective that describes the second one. Something better than non-cyclic. I think there is an actual word.
Thanks. I'm not intending to name the compound. I have the name. I am describing a mechanism and I am looking for an adjective (one word) that specifies the particular amine group and differenciates it from the other one.
Answer : Would 'exocyclic' be appropriate?
