Organic chemistry
can someone me place the correct ones in the correct nomenclature?

The last figure (with the name 3-Chloro-2-iodo-4-methylhexane) is correct.

Explanation:

---> It gives the correct numbering of the positions of each Iodine Chlorine and Methyl which are attached at 2, 3 and 4 respectively

---> and also the names are given on alphabetical order (i.e. first Chlorine then Iodine and then Methyl)

most sediment washes or falls into the river as a result of mass movement and runoff. other sediment eroded from the bottom or sides of the river.

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.
