Draw main conformation of n-butane obtained by rotation around C-2 and C-3 also give the names of these conformations. Which of these conformation is most and which is the least stable and why?

"As alkanes increase, the conformation possibilities also increases. The lowest energy configuration, called the anti-periplanar (or anti)configuration, is the one in which the two large methyl groups are as far apart as possible.
When rotation occurs around the C(2)-C(3) bond, another eclipsed (anti-clinical) conformation is achieved in which two Me-H interactions and one H-H interaction occur.
The syn-periplanar configuration is less stable whereas the anti-periplanar configuration is more stable."
