Expert Solution

substance Absolute entropy (S⁰) at 25⁰C

[ J\(molk) ]

1) C2H2 (g) 200.95

2) Ne (g) 146.3

3) H2O (l) 70.04

4) C2H5OH (l) 160.67

5) C4H10 (g) 310.22

Butane [C4H10( g)] has greatest absolute entropy among the above all substances.We know that gases has more entropy than liquid because of c-c sigma bond free rotation at 25⁰C.
