This is the skeletal structure.

The question is confusing since we do not show the hydrogen atoms in the skeletal structure, however, we do for the condensed which is the following:

#CH_3CH(CH_3)CH_2C-=CCH_2CH(CH_3)CH_3#

The tertiary carbons are #C_2# and #C_7#.

Regarding the rotation.
Rotation is allowed around all bonds except for the triple bond between #C_4-=C_5# it is restricted.
