How To Easily Describe Your First Cyclohexane Chair Using the "Parallelogram Technique"

At present that we've had an aerial tour of the cyclohexane chair, nosotros're going to motility on to a very of import skill:how to properly draw one of these beasties.

In that location are several techniques for properly draw a cyclohexane chair.

In this video, I walk through what I consider to be the well-nigh completely idiot-proof mode to draw a chair, by first drawing a parallelogram (something yous should already know how to do). Using this as the "base" of our chair, we and then draw flaps moving upwardly and down (representing the head and footrest), then put in the axial and equatorial groups.

Chiefly, nosotros tin can utilize this method to draw a chair in either the "left hand" or the "right manus" version of a cyclohexane chair, which becomes important, once nosotros learn almost chair flips (that's next!)

In time and with a petty bit of practice, you won't demand to draw the parallelogram to guide you. Think of it as a set of training wheels that you volition later discard one time you don't need them anymore.

How Non To Draw The Cyclohexane Chair Conformation: 4 Examples

Having an piece of cake-to-think technique is crucial.

Otherwise, your commencement few attempts in cartoon a cyclohexane chair from retentiveness might see you end up with one of these "variations" from a rogue's gallery of 4 means to screw upward drawing a cyclohexane chair (and don't feel bad – we've all done information technology . The trick is to make all the necessary mistakesbefore you accept your midterm).

Bad Cyclohexane Chair #1: Crow's Foot

crows foot cyclohexane how not dto draw a chair bond angles are not tetrahedral What's incorrect? The axial and equatorial positions on the circled carbon are drawn in the wrong direction, leading to the carbon having a "crow'south human foot" appearance. Bond angles in this carbon is not properly tetrahedral – furthermore, the side by side carbons are eclipsed, not staggered!

How to gear up:Flip the groups on the carbon. The "axial down" grouping should be drawn equally "axial up" and the "equatorial up" group should be fatigued as "equatorial downwards". Remember, the axial groups alternating "up, downward, up, down, up downwards" throughout the ring.

Bad Cyclkohexane  Chair #2: Crow's Foot (slight return)

how not to draw a cyclohexane crows foot switched axial and equatorial What's wrong?Another crow's foot, although drawn on the "head rest" of the chair.

How to fix:switch "axial down" to "axial upwardly" and "equatorial up" to "equatorial down". And then y'all'll encounter that your axial groups now alternate up downwardly upwards down up down again (like they should)

Bad Cyclohexane Chair #3: "The Lightning Commodities" [h/t Chemjobber]

how not to draw a cyclohexane chair lightning bolt too thin What'south wrong?The axial and equatorial positions are drawn in properly, merely the chair is drawn then thinly that the front carbons obscure the groups on the back carbons.

How to set: The angles at the "headrest" and "footrest" are also acute; open them up a chip. Also, stagger the two front carbons and the 2 back carbons so that they're not straight in forepart of each other.

Bad Cyclohexane Chair #4: "Mr. Fatty"

how not to draw a cyclohexane chair mister fatty improper dimensions What's wrong?Though all the centric and equatorial positions are drawn properly, this diagram strains the imagination for a cyclohexane supposedly consisting of six equal sides.

How to prepare:Pretty straightforward – simply don't draw the vertical bonds so long!
