Why is sound transmission in water much more efficient than in air?

Answer

Liquid molecules are closer together, providing a degree of incompressibility.

Liquid molecules are packed tighter than gas molecules, resulting in stronger forces of attraction and lower compressibility, allowing vibrational energy to be passed along more efficiently.
