Answer:

Trimethylborane.

Explanation:

So, you must find the name of

#(color(blue)("CH"_3))_color(red)(3)"B"#

Notice that the compound given to you contains #color(red)(3)# methyl groups, #color(blue)("H"_3 "C"-)#, bonded to an atom of boron, #"B"#.

You can think of these methyl groups as replacing the hydrogen atoms in borane, #"BH"_3#, which looks like this

Instead of a central boron atom bonded to three hydrogen atoms, you have it bonded to three carbon atoms.

The show that you're dealing with #color(red)(3)# methyl groups, you must use the Greek prefix tri.

You will have

#(color(blue)("CH"_3))_color(red)(3)"B" -> color(red)("tri")color(blue)("methyl")"borane"#
