The RAND function returns numbers from the interval [0,1), and if you need to generate numbers from another interval, you should use the following formula: =RAND() * (bâa) + a. This will return random numbers from the interval [a,b) - greater than or equal to a, and less than b.
At the time, 5.4 was made available as a beta release alongside the stable 5.3.4 release. Now that 5.4 has become the latest stable Unity release, it seems the company intends to keep the program going a beta version of Unity 5.5 is slated to debut in the near future. source.
When the double bond is substituted with another alkyl group, the electrons in the carbon-hydrogen bond of that alkyl group can stablilze the vacant anit-bonding Pi orbital of the double bond. This is call hyperconjugation.This leads to a net positive interaction, which makes the double bond more stable.ubstituted alkenes are more physically stable. The fact that the activation energy for a tri subst. alkene is lower is because any carbocation intermediate is more stable with increasing substitution.
