Assuming that all the four valencies of carbon atom in propane pointing towards the corners of a regular tetrahedron, If the distance between the terminal carbon atoms in propane is $$X$$ $$\mathring { A } $$. Find $$100X$$. Given, $$C-C$$ bond length is $$1.54\mathring { A } $$, (sin $$109.5$$ is $$0.94$$)

A
B
C
D

Solution

The distance $$X$$ between the terminal $$C$$ atoms is given by the expression $$2 \times C-C _{bond \ length} \times sin 109.5 =2 \times 1.54 \times 0.94 = 2.9 \ A^0$$.

Hence, $$100X = 100 \times 2.9 \quad A^0 = 290 \quad A^0$$.
