Question

1. drag and drop the molecular shapes with the images. choices linear bent tetrahedral trigonal planar trigonal pyramidal

Explanation:

1. First molecule: The central atom is bonded to two other atoms in a straight line, so its shape is linear.
2. Second molecule: The central atom is bonded to four other atoms (or groups) in a three - dimensional shape where the atoms are at the corners of a tetrahedron, so its shape is tetrahedral.
3. Third molecule: The central atom is bonded to three other atoms (or groups) in a flat, triangular arrangement, so its shape is trigonal planar.

Answer:

First molecule: linear
Second molecule: tetrahedral
Third molecule: trigonal planar
