Answer:
the 4s subshell is lower in energy than the 3d subshell
Explanation:
In the element number 24 which is chromium
the electronic configuration should be according to Aufbau principle
will be = ![1s^22s^22p^63s^23p^64s^23d^4](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E23p%5E64s%5E23d%5E4)
but in reality it is = ![1s^22s^22p^63s^23p^64s^13d^5](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E23p%5E64s%5E13d%5E5)
The 6 electrons in the outermost shell will be divided as 5 in 3d subshell and 1 in 4s shell, because half filled orbital
will be more stable than
.
Ethanol is a polar molecule containing hydrogen bonds at the OH groups. These bonds are much stronger and therefore take much more energy to break, hence the higher melting and boiling points
Ethane on the other hand is non-polar as it is a hydrocarbon and only contains London Dispersion forces between molecules, which are the weakest of the intermolecular forces, meaning it is easy to break them.
Answer:
Attached below
Explanation:
Attached below is the required diagrams
From the attached diagram ; Compounds 1 and 2 are achiral ( i.e. stereoisomers aren't possible here )
Compound 3 : ( 1S, 2R ) - 1 - chloro-2-methylcyclopropane
Compound 4: ( 1R , 2S ) - 1- chloro-2-methylcyclopropane
Compound 5: ( 1R, 2R ) - 1 - chloro-2-methylcyclopropane
Compound 6: ( 1S, 2S ) -1- chloro-2- methyl cyclopropane
Answer: It shows that light acts like a wave, but also to demonstrate that electrons can act like waves and create interference patterns.
