Ammonia (240 K) has a higher boiling point than phosphine (190 K) and then the boiling point increases down the group because of increase in size. In PH 3 and other hydrides, the intermolecular forces are Van der Waals' forces. These van der Waals' forc..
Ammonia (240 K) has a higher boiling point than phosphine (190 K) and then the boiling point increases down the group because of increase in size.

Another way of tailoring properties is to vary the arrangement of the side groups on the backbone. This is the tacticity of the polymer. And it is to a polymer what the stereoisomerism is to individual molecules. And that lastly, we looked at the shape of the backbone itself, different conformations, and this is owing to the rotational capability of the carbon-carbon bond. And, at the very end of the lecture, we looked at two forms of formation ...
see that I can put a symmetry plane here. And, what do I have? I've got both of my methyl groups above the carbon-carbon double bond. And, both of the hydrogens below the carbon-carbon double bond. But another way I could have set up the structure, again, there's the carbon-carbon double bond. Let's put the 120 angles, will put the methyl group above the carbon-carbon bond on the left side, but below the carbon-carbon bond on the right side. And then, we'll do the complementary ...
