Work Step by Step
let's predict the molecular structures for the given compounds:
a. ICl5 (Iodine Pentachloride)
The molecular structure of ICl5 is a square pyramidal geometry.
- The central iodine (I) atom is bonded to five chlorine (Cl) atoms.
- The bond angles around the central iodine atom are approximately 90 degrees, forming a square-based pyramid.
- The lone pair of electrons on the iodine atom occupies the apex of the pyramid, resulting in the square pyramidal geometry.
b. XeCl4 (Xenon Tetrachloride)
The molecular structure of XeCl4 is a square planar geometry.
- The central xenon (Xe) atom is bonded to four chlorine (Cl) atoms.
- The bond angles around the central xenon atom are approximately 90 degrees, forming a square planar arrangement.
- The lone pair of electrons on the xenon atom occupies the space above and below the square plane, resulting in the square planar geometry.
c. SeCl6 (Selenium Hexachloride)
The molecular structure of SeCl6 is an octahedral geometry.
- The central selenium (Se) atom is bonded to six chlorine (Cl) atoms.
- The bond angles around the central selenium atom are approximately 90 degrees, forming an octahedral arrangement.
- There are no lone pairs of electrons on the selenium atom, allowing for the full octahedral geometry.
