Answer:
mass number
Explanation:
yeah mass number is the total of protons and neutrons
for example carbon has 12 proton and 12 neutrons therefore it's mass number is 24
i hope this is what you're looking for
Answer:
Product A and B : (2R,3S)-2,3-diethyloxirane and (2S,3R)-2,3-diethyloxirane.
Explanation:
A double bond is converted to an oxirane through oxidation by peracids e.g. mCPBA (meta-chloroperoxybenzoic acid).
Epoxidation can occur at both face of double bond result in formation of two stereoisomers.
Product A and B : (2R,3S)-2,3-diethyloxirane and (2S,3R)-2,3-diethyloxirane
Both A and B contain plane of symmetry. Hence, both the products are achiral. So, they do not rotate the plane of polarization of plane polarized light.
Answer:- It's not correct because the values of n and l are same.
Explanations:- The four quantum numbers are n, l, ml and ms where n stands for Principal quantum number and has values like 1, 2, 3 and so on.
l stands for azimuthal quantum number and has values from 0 to (n-1) where n is principal quantum number.
For the given set of quantum numbers, value of n is 3. So, the possible values of l would be 0,1 and 2.
The value of l for the given set of quantum numbers is 3 which is the reason why the given set is not possible.
