Which molecule or ion has a linear shape?A.ClO4−B.PH3C.BeCl2D.PCl5SUBMITarrow_backPREVIOUS

The molecule that has a linear shape is BeCl2.

Here's why:

A. ClO4−: This ion has a tetrahedral shape. The central atom (Cl) is surrounded by four oxygen atoms, forming a tetrahedron.

B. PH3: This molecule has a trigonal pyramidal shape. The central atom (P) is surrounded by three hydrogen atoms and one lone pair of electrons, forming a pyramid.

C. BeCl2: This molecule has a linear shape. The central atom (Be) is surrounded by two chlorine atoms, forming a straight line.

D. PCl5: This molecule has a trigonal bipyramidal shape. The central atom (P) is surrounded by five chlorine atoms, forming a bipyramid.
