The molecular orbital diagram of HF looks different than most other diatomic species because the electronegativity difference between H and F is so large. The 1s atomic orbital of H interacts with just one of the 2p atomic orbitals of F to form a bonding o molecular orbital and an antibonding o molecular orbital.
