IGNORE MY FIRST POST. I CORRECTED THIS ONE

Write IUPAC name of the following alkanes:

1. (CH3)3-C-CH2-CH2-CH3
Would the name be 2-dimethylpentane?

2. CH3CHCH2CHCH2CH2CH3 with a CH3 attached to the 2nd carbon and the 4th carbon.
Would the name be 2,4-dimethylheptane?

3. CH3-C-C-CH3 with a CH3 attached to the top and bottom of both C (4 CH3 total).
Would the name be 2,3-tetramethylbutane?

If someone could please check to see if my answers are right so I know if I am doing this correctly, I would very much appreciate it. Thanks!
