The solute has to be hydrophilic, (water loving).
Answer:
There will be 3 peaks.
Relative height of the atomic peaks would be; 158, 160 and 162
Explanation:
We are told that Bromine has two isotopes namely 79Br and 81Br in a 1 : 1 ratio (50 : 50).
This means that a compound which contains 1 bromine atom will have two peaks in the molecular ion region but it depends on which bromine isotope is contained in the molecular ion.
Thus;
Relative height of atomic peaks is given by;
m/z = 79Br¯ 79Br+ = 158
79Br¯ 81Br+ = 160
81Br¯ 81Br+ = 162
The names of these constitutional isomers are cyclopentane, methylcyclobutane, ethylcyclopropane, and 1,1-dimethylcyclopropane.
Constitutional isomers have the same molecular formula. This means that they have the same number of carbon and hydrogen atoms, with a general formula of:

When we consider the possible structures, the first option is cyclopentane, the simplest five-membered ring. When we reduce the ring to four carbons, we have the methylcyclobutane and when we reduce it to three carbons, we can arrange the other two carbons in an ethyl group or we can put two methyl groups on a single carbon atom to get the final two constitutional isomers.
