Re: Z-1-chloro-2-methyl-1-butene
It is not methylene because methylene refers to a group in the middle of the carbon chain (-CH2-). The CH3 attached to one of the carbons in the double bond is a substituent by the rule that is discussed in this section, and is therefore called a methyl group. There is no "ethyl" in the n...

The ionization here happens mostly within the first two groups.
In the first group, when the first ion is removed, we have to remove one ion from the core noble gas, which would be very hard, because it's already a stable formation.
