The reaction of 2 methyl butane with chlorine would yield 5 mono chloro derivatives.
Step-by-step explanation
The organic compound of 2 methyl butane will have 5 C-H groups.
As butane means 4 CH group and one methyl at 2nd position means one more CH group, so totally 5 CH group is present.
These 5 CH group can react with chlorine and form 5 mono chloro derivatives like CH3Cl, CH2Cl etc.
The chirality present in the anti-bonded carbon atoms leads to the exhibition of stereoisomerism while forming mono chloro derivatives.
Thus, it can be confirmed that 5 mono chloro derivatives will be produced when 2 methyl butane reacts with chlorine.
