An isotropic helicoid is a shape that is helical, so it rotates as it moves through a fluid, and yet is isotropic, so that its rotation and drag are the same for all orientations of the particle. It was first proposed by Lord Kelvin in 1871, who described a specific geometry with twelve vanes placed around a sphere. As of 2021, such a phenomenon has yet to be proven by researchers. (Wikipedia).
Isopropyl Chloride Synthesis: Making an Alkyl Halide | DIY Gasoline (Part 1)
Isopropyl chloride is a clear, volatile liquid with an extremely low boiling point (only 36 degrees Celsius). It belongs to a family of chemicals known as alkyl halides, which have a variety of uses in organic chemistry, such as in the Williamson ether synthesis or the Grignard reaction. I

What Are Structural Isomers? | Organic Chemistry | Chemistry | FuseSchool
What Are Structural Isomers? Different forms of the same molecule are known as structural isomers; they have the same molecular formula but are different 'shapes'. In this video we will look at some different structures of butane - so they all have 4 carbons but just arranged differently
