So, if you draw the staggered conformation of the given molecule then this is the atoms which are above the plane of paper and this is the one which is below the plane or away from the viewer.
00:23
So, this has the energy 2 into 0 .85 which is 1 .7 kilocalorie per mole and it is a higher energy conformation or we can say it is less stable because stability is mostly related to the energy.
00:50
Energy so another molecule can be enriched the atoms can be arranged in this manner this is ch3 ch2 ch3 h h h and this is ch2 ch3 so this is 0 .85 5 kilocalorie per mole and this is of lowest energy means more or higher stability is there so the groups c3 and c4 c3 are hydrogen and ch3 and ch2 whereas c4 here are hydrogens and ch3ch3.
01:54
So as we have mentioned h here, so these h represents c3c4 that all nomenclature we have given here.
02:08
Next if we draw about the eclipsed form of this, so eclipsed form will be of two way hydrogen one below the other, so this is ch3, ch2, ch3 and hydrogen and this is ch3.
02:33
So this is another conformer of eclipsed.
02:39
It will be like this...
