Final answer:
A covalent compound with a pyramidal shape likely has a central atom bonded to three other atoms plus one lone pair, creating a trigonal pyramidal molecular shape; NH3 is a typical example.
Step-by-step explanation:
When describing a covalent compound with a pyramidal shape, we refer to a molecule that is likely to have a central atom bonded to three other atoms with a lone pair of electrons on the central atom. This leads to a trigonal pyramidal molecular shape. A common example of such a molecular formula is NH₃, where nitrogen (N) is the central atom, bonded to three hydrogen (H) atoms and has one lone pair of electrons, resulting in a trigonal pyramidal shape according to the VSEPR theory.
