If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. For chemistry homework. 10 months ago. The observed H-O-H bond angle in water (104.5°) is less than the tetrahedral angle (109.5°); one explanation for this is that the non-bonding electrons tend to remain closer to the central atom and thus exert greater repulsion on the other orbitals, pushing the two bonding orbitals closer together. 90 degrees. 2 0. For similar reasons, $\ce{HOF}$ will have a bond angle closer to $109.5^\circ$. 2.

The bond lengths and angles of an electronically excited molecule usually differ from the ground-state values. Submit Rating . Normally the axial "F"-"S"-"F" angle would be 180^@ (because of course they are exactly opposite/antiparallel to each other), but it becomes 173.1^@, and normally the equatorial "F"-"S"-"F" angles are 120^@ (because the horizontal plane would distribute three connected atoms evenly over 360^@), but they become 101.6^@. 1 Answer +1 vote . Check Planes to see them. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. Right off the bat, you shouldn’t use the word “logical” when talking about chemical bonds. This angle is usually measured in degrees, further calculated using the spectroscopic method.

In a linear model, atoms are connected in a straight line, and a bond angle is simply the geometric angle between two adjacent bonds. Previous question Next question The ideal bond angle is 109.5, but because that lone pair is there, all you'd have to really say is, you would expect the bond angle to be less than 109.5. In this example we use the PV function to calculate the present value of the 6 equal payments plus the $1000 repayment that occurs when the bond reaches maturity. The F–S–F bond angles in SF6 are: a. (Show diagram of C2H4) Each peptide bond holds six atoms in a plane. The value of an asset is the present value of its cash flows.
