A student used Valence Shell Electron Pair Repulsion (VSEPR) theory to predict the shapes and bond angles of five species. The predictions are shown in the table.
| Row |
Species |
Predicted shape |
Predicted bond angle |
| P |
\(\mathrm{CH_4}\) |
Square planar |
\(90^\circ\) |
| Q |
\(\mathrm{H_2O}\) |
Bent (V-shaped) |
\(109.5^\circ\) |
| R |
\(\mathrm{BF_3}\) |
Trigonal pyramidal |
\(107^\circ\) |
| S |
\(\mathrm{NH_3}\) |
Trigonal pyramidal |
\(120^\circ\) |
| T |
\(\mathrm{NH_4^+}\) |
Tetrahedral |
\(109.5^\circ\) |
Which row or rows contain
both a correct shape
and a correct bond angle?
