alkaline earth difluoride decreasing bond angle
« on: November 24, 2009, 01:05:23 PM »
The bond angles of the gas-phase difluorides of Group 2 elements change from 180 degree to around 90 degree going down the group. Rationalize the trend in the F–metal–F bond angles in terms of the relative weightings of the s-orbital and of the p-orbital in the hybridization of the central atom.
Thanks.

first think of what kind of hybridization corresponds to what geometry

Thanks.

Are you sure it is Group 2 elements?
