A way to explain it is that back then all the continents were together but soon after drifted apart the were in the same place sort of put they drifted apart so that's sorta what happened. Hope that helps a little
Unsaturation (IHD) 2 hydrogen Needed
IHD = [(2n+2) -H]/2
(H: X=1, N=-1, O= zero)
Unsaturation:
Double bonds = 1
Rings = 1
Triple Bonds = 2
The degrees of unsaturation in a molecule are additive — a
molecule with one double bond has one degree of unsaturation, a molecule with
two double bonds has two degrees of unsaturation, and so forth.
False, our tongue and nose work together
Varuable, In algebra, a symbol (usually a letter) standing in for an unknown numerical value in an equation :)
Answer:
Structural
Explanation:
Isomerism is the existence of two or more compounds with the same molecular formula but different molecular structures due to the difference in the arrangement of atoms or spatial orientation of atoms.
Isomers have the same molecular formula but differs in their structural arrangement.
In organic chemistry, Isomerism can orginate from different arrangement of atoms.
It can be carbon chain length known as chain isomerism. Here, the carbon length is changed and arranged in different ways.
We can also have position isomerism which entails the position of the functional group in the structure.
It can also be functional group isomerism which deals with the possible arrangement of the group on the chain.
