Ans. Constitutional isomers.

Sol. In the first Newman projection the front and back carbons each carry CH₃, H, H: the molecule is n-butane, CH₃CH₂-CH₂CH₃. In the second the front carbon carries two CH₃ and one H while the back carbon carries three H: the molecule is 2-methylpropane, (CH₃)₂CH-CH₃. Same molecular formula C₄H₁₀, different connectivity : constitutional isomers.
