Which explanation best predicts which species has the smaller bond angle, ClO4− or ClO3−. Which explanation best predicts which species has the smaller bond angle, or . ClO4− will have the smaller bond angle since the chlorine atom must expand its octet to accommodate four oxygen atoms, thus increasing the potential repulsion between each bonding pair of electrons. ClO4− will have the smaller bond angle since it has more electron groups with a total of four electron groups, and more...
