When e2 becomes e4, e1 becomes e1e2 and not e1 because the new position of e2 is now occupied by the piece that was previously on e1. Therefore, to indicate the movement of the piece from e1 to e2, the notation e1e2 is used. This helps to clearly show the movement of the piece from its original position to its new position on the chessboard. **

Yes, an SN1 and E1 reaction would be favored in this scenario. The presence of a tertiary alkyl halide suggests that the reaction will proceed through an SN1 or E1 mechanism due to the stability of the carbocation intermediate that forms. Additionally, the solvent being used is likely polar protic, which is favorable for SN1 and E1 reactions. Overall, the conditions provided are conducive to favoring an SN1 or E1 reaction. **

To determine if e1 and e2 are orthogonal to each other, we need to calculate their dot product. If the dot product of e1 and e2 is zero, then they are orthogonal. If the dot product is not zero, then they are not orthogonal. The dot product of e1 and e2 is equal to 0, therefore, e1 and e2 are orthogonal to each other. **

The BMW E1 Z15 was never produced because it was a concept car designed to showcase BMW's vision for the future of electric mobility. At the time of its unveiling in 1991, the technology and infrastructure for electric vehicles were not advanced enough to support mass production of the E1 Z15. Additionally, the market demand for electric vehicles was not as strong as it is today, making it financially unviable for BMW to invest in producing the E1 Z15. As a result, BMW focused on other projects and did not pursue mass production of the E1 Z15. **
