Question

question 4 of 25
which term describes this molecular shape?
x a x
x
a. trigonal planar
b. linear
c. trigonal pyramidal
d. tetrahedral

Explanation:

In a trigonal planar molecular shape, the central atom (A) is bonded to three other atoms (X) and there are no lone - pairs on the central atom, and the atoms are arranged in a flat, triangular shape. The given structure with three X atoms around the central A atom fits this description. A linear shape has two atoms bonded to the central atom in a straight line. A trigonal pyramidal shape has a central atom with three bonded atoms and one lone - pair. A tetrahedral shape has a central atom bonded to four other atoms.

Answer:

A. Trigonal planar
