The B-X bond distance in BX3 is shorter than the theoretically expected value due to the presence of strong covalent bonding and the involvement of p-orbitals in bonding. This results in significant orbital overlap, which increases electron density between the boron and halogen atoms, effectively shortening the bond length. Additionally, the presence of lone pairs on the halogen can lead to greater electron repulsion, further stabilizing the bond and contributing to the shorter distance.
What else can I help you with?
Why B-X bond distance in BX3 is shorter than its theoritically expected value?
because it is stonger of all elements
Can you compare an expected value to a calculated value?
Yes, an expected value represents the theoretical average outcome of a random variable based on its probability distribution, while a calculated value is the result obtained from actual observations or experiments. Comparing the two can help assess the accuracy of predictions and the reliability of the model used to derive the expected value. Discrepancies between the expected and calculated values can indicate potential biases, errors in the model, or the influence of random variation in the data.
How to get expected frequency value in chi square test?
For goodness of fit test using Chisquare test, Expected frequency = Total number of observations * theoretical probability specified or Expected frequency = Total number of observations / Number of categories if theoretical frequencies are not given. For contingency tables (test for independence) Expected frequency = (Row total * Column total) / Grand total for each cell
How do you find percent difference of experiment and thery?
To find the percent difference between an experimental value and a theoretical value, first calculate the absolute difference by subtracting the theoretical value from the experimental value. Then, take the absolute value of this difference. Next, divide the absolute difference by the theoretical value, and finally multiply the result by 100 to convert it into a percentage. The formula is: (\text{Percent Difference} = \left( \frac{|\text{Experimental} - \text{Theoretical}|}{|\text{Theoretical}|} \right) \times 100).
How do i find expected value in a martingale system?
The expected value of a Martingale system is the last observed value.

How do you find absolute discrepancy...this is different from percent discrepancy?
Absolute discrepancy is the absolute difference between an observed value and a theoretical or expected value. To find absolute discrepancy, you simply subtract the observed value from the theoretical value and take the absolute value of the result. This measurement is different from percent discrepancy, which calculates the difference as a percentage of the theoretical value.

How do you compute a percent error?
% error = |experimental value - theoretical value|/theoretical value * 100% It is the absolute value of the differe nce betwee n the experime ntal a nd theoretical values divided by the theoretical value multiplied by 100%.
How do you show percent error?
Percent error = (actual value - theoretical value) / theoretical value * 100%
Formula for percent error?
Percent Error = {Absolute value (Experimental value - Theoretical Value) / Theoretical Value }*100
How does the experimental result differ from the theoretical in terms of accuracy?
Provided that the correct model is used, the theoretical probability is correct. The experimental probability tends towards the theoretical value as the number of trials increases.Provided that the correct model is used, the theoretical probability is correct.

Is the expected value the same as the standard deviation?
No. The expected value is the mean!

What is the meaning of expected value in a probability distribution?
The expected value is the average of a probability distribution. It is the value that can be expected to occur on the average, in the long run.

The expected value of a Martingale system is the last observed value.
