Decomposition is where one compound splits into two or more
Single replacement is when an element switches with another element in a compound
Combustion is when something combines with oxygen to produce water and carbon dioxide
Double replacement is like single but two compounds switch their elements
Answer: two signals split into four and three respectively
The spectrum of CH3CH2OCH2CH3 is shown in the image attach. The large multiplicity arises from spin orbit coupling which arises because of interaction of proton magnetic field with bonding electrons. In the spectrum the two CH3 groups are split by CH2_and vice versa. The ethyl groups are chemically and magnetically equivalent but are still split by adjacent protons.
It is electrical to mechanical
