Given below are two statements :
Statement (I): Neopentane forms only one monosubstituted derivative.
Statement (II): Melting point of neopentane is higher than n-pentane
In the light of the above statements, choose the most appropriate answer from the options given below
Both Statement I and Statement II are correct
-
I true: Neopentane, C(CH₃)₄, is highly symmetric; all 12 hydrogens are equivalent → only one monosubstituted derivative.
-
II true: Its high symmetry improves packing, giving a higher melting point than n-pentane.
Thus both statements are correct → (B)
