What is the IUPAC name for the following?
#color(white)(mmmmmmml)"CH"_2#
#color(white)(mmmmmmmll)"||"#

The preferred IUPAC name is 2-methyl-3-methylidenepentane.
Explanation:
The latest (2013) version of the IUPAC Blue Book on organic nomenclature says:
The principal chain has the greater number of skeletal atoms.
Thus, chain length takes precedence over unsaturation.
We name your compound as a substituted pentane.
The
2-methyl-3-methylidenepentane.
